Mozambique Spitting Cobra (Naja mossambica) Care Sheet
The Mozambique Spitting Cobra (Naja mossambica) is a dangerously venomous African elapid native to southern and south-eastern Africa. It is one of the best-known spitting cobras in specialist venomous-reptile collections and is notable for its ability to project venom defensively toward the face and eyes of a perceived threat.
This defensive behaviour creates an additional husbandry hazard beyond the risk of a bite. Enclosure design, routine servicing and emergency planning must therefore take into account the possibility of venom projection as well as direct envenomation.
Mozambique Spitting Cobras are primarily terrestrial, active and highly alert snakes. They occur across a range of savannah, scrub, dry woodland, rocky and human-modified habitats and often make use of rodent burrows, termite mounds, fallen timber and other ground-level retreats.
They are powerful, inquisitive animals that require substantial usable floor space, multiple secure hides, strong ventilation, appropriate thermal gradients and carefully designed secondary containment.
This species is capable of severe and potentially life-threatening envenomation and should only be maintained by appropriately experienced specialist venomous-reptile keepers with secure facilities, established emergency procedures and all legally required permissions.
This care sheet provides comprehensive husbandry guidance. It is not a venomous-snake handling or restraint manual.
Captive-bred animals of documented provenance should be strongly preferred.

Important Venomous Species Warning
The Mozambique Spitting Cobra is a dangerously venomous snake.
Any suspected bite requires:
IMMEDIATE EMERGENCY MEDICAL ASSESSMENT.
In addition, projected venom entering the eyes is a medical emergency because it can cause severe pain and potentially serious ocular injury.
Before acquisition, the keeper should already have:
- Appropriate specialist venomous-reptile experience
- Secure purpose-built accommodation
- Secondary containment
- Effective escape prevention
- Written emergency procedures
- A specific eye-exposure emergency plan
- Appropriate veterinary arrangements
- Knowledge of suitable emergency medical facilities
- An accidental-escape plan
- A plan should the primary keeper become incapacitated
- Appropriate legal permissions where required
- A responsible backup person who knows what species are present and how to summon suitable assistance
These arrangements should exist before the animal enters the facility.
Defensive Venom Projection
Mozambique Spitting Cobras can deliberately project venom toward the face of a perceived threat.
The eyes are an especially vulnerable target.
This behaviour means routine husbandry must account for risk from:
- Venom projected through an open enclosure
- Venom reaching the keeper during defensive behaviour
- Venom contaminating nearby surfaces
- Secondary transfer from contaminated equipment
The species should therefore never be treated like a non-spitting cobra simply because the enclosure is secure.
Eye Exposure
If venom enters the eye:
IMMEDIATE IRRIGATION WITH LARGE QUANTITIES OF CLEAN WATER OR STERILE SALINE IS ESSENTIAL, FOLLOWED BY URGENT MEDICAL ASSESSMENT.
Do not delay irrigation while searching for specialist products.
Do not rub the eye.
Contact lenses should be removed if this can be done easily during irrigation.
Persistent:
- Pain
- Redness
- Light sensitivity
- Blurred vision
- Excess tearing
- Corneal symptoms
require urgent medical evaluation.
Projected venom on intact skin is generally a different hazard from venom entering the eye or bloodstream, but contaminated skin and equipment should still be washed thoroughly.
Species Overview
Mozambique Spitting Cobras occupy a wide range of warm southern African habitats.
These can include:
- Savannah
- Bushveld
- Scrub
- Dry woodland
- Rocky ground
- Agricultural land
- Human-modified environments
- Areas around rodent burrows and termite mounds
They commonly utilise:
- Burrows
- Hollow logs
- Rock crevices
- Dense vegetation
- Ground debris
Captive accommodation should therefore prioritise:
FLOOR SPACE + SECURE RETREATS + THERMAL CHOICE + MODERATE HUMIDITY + GOOD VENTILATION + SAFE VISUAL ACCESS.
Adult Size
Adults commonly reach approximately:
3.5–5 ft (1.1–1.5 m).
Large individuals can exceed this.
The species is muscular and active.
Enclosure dimensions should therefore reflect:
- Length
- Body mass
- Activity
- Behavioural needs
rather than simply providing enough room for the snake to coil.
Lifespan
With excellent captive husbandry:
15–20+ YEARS
may be achievable.
This should be treated as a long-term specialist commitment.
Colour & Pattern
Typical Mozambique Spitting Cobras may show:
- Brown
- Grey-brown
- Olive
- Dark brown
- Reddish tones
- Paler ventral colouration
- Dark throat markings
Juveniles may show stronger contrast than adults.
Appearance can vary with:
- Locality
- Age
- Genetics
- Individual variation
Colour should never be used as the sole method of species identification.
Enclosure
For one adult, approximately:
5 × 2.5 × 2.5 ft
(approximately 150 × 75 × 75 cm)
should be considered a practical starting point.
Large individuals benefit from:
6 ft (180 cm) OR MORE OF ENCLOSURE LENGTH
where safe specialist management permits.
The enclosure should allow:
- Meaningful movement
- Thermoregulation
- Multiple retreat choices
- Exploration
- Different substrate zones
- Access to water
- Movement between open and covered areas
Why Floor Space Matters
Mozambique Spitting Cobras are active terrestrial snakes.
Meaningful floor space allows:
- Locomotion
- Exploration
- Thermoregulation
- Different resting positions
- Natural ambush behaviour
- Environmental choice
A long enclosure is more useful than excessive unused height.
Low-Level Climbing Opportunities
The species is primarily terrestrial but can climb.
Useful low structures include:
- Broad logs
- Thick branches
- Cork
- Stable rockwork
- Raised shelves
These should supplement rather than replace floor space.
Security
The enclosure must be:
- Robust
- Escape-resistant
- Lockable
- Resistant to accidental opening
- Appropriately identified
- Located within a secure dedicated room or facility
Inspect:
- Door gaps
- Sliding tracks
- Hinges
- Locks
- Ventilation openings
- Cable ports
- Service openings
- Lighting access points
Security must also consider venom projection through openings.
Large ventilation gaps or exposed service ports should not create an easy line of projection toward people in the room.
Secondary Containment
The primary enclosure should exist within:
A SECURE SECONDARY ROOM OR FACILITY.
The primary enclosure should not be the only barrier between the animal and an uncontrolled area.
The surrounding room should:
- Prevent unauthorised access
- Reduce escape routes
- Allow controlled visual assessment
- Form part of the emergency containment plan
Routine Husbandry Design
Routine tasks should be possible while minimising unnecessary close exposure.
These include:
- Water servicing
- Spot cleaning
- Substrate maintenance
- Equipment checks
- Visual health assessment
Specialist enclosure designs incorporating secure retreat compartments can significantly improve routine management.
The principle should be:
DESIGN OUT UNNECESSARY EXPOSURE.
Visual Barrier Considerations
Because this species can project venom defensively, visual barriers can be particularly useful.
Appropriate enclosure design may reduce direct face-to-face confrontation during routine servicing.
This does not mean the enclosure should be visually sealed.
The keeper must still be able to:
- Locate the snake
- Assess health
- Check equipment
- Confirm containment
Juvenile Enclosures
Juveniles require smaller secure accommodation scaled appropriately to body size.
Provide:
- Secure terrestrial hides
- Appropriate thermal gradient
- Dry-to-moderate substrate
- Fresh water
- Good ventilation
- Low structural enrichment
Hatchlings are:
VENOMOUS FROM HATCHING.
Young animals may also display defensive venom projection.
Enclosure design should therefore account for both:
BITE RISK
and:
EYE-EXPOSURE RISK.
Temperature & Heating
Mozambique Spitting Cobras require warm conditions but still need meaningful thermal choice.
Basking Surface
Approximately:
30–32°C (86–90°F).
Warm-Side Ambient
Approximately:
26–28°C (79–82°F).
Cool Retreat
Approximately:
22–24°C (72–75°F).
Night
Approximately:
20–23°C (68–73°F).
A modest night-time drop is appropriate.
Thermal Gradient
Provide:
BASKING AREA → WARM ZONE → MODERATE ZONE → COOL RETREAT.
The snake must be able to leave the warmest area completely.
Avoid Uniform Heat
Do not maintain the entire enclosure at approximately:
30–32°C.
Wild snakes avoid excessive heat through:
- Burrows
- Shade
- Cooler ground
- Nocturnal activity
- Dense vegetation
Heating Equipment
Suitable options can include:
- Secure overhead radiant heating
- Appropriately guarded basking lamps
- Radiant heat panels
- Controlled room heating
All heat sources should be:
- Securely installed
- Appropriately controlled
- Protected from animal contact
- Independently monitored
Avoid:
- Hot rocks
- Exposed heating elements
- Uncontrolled heaters
Temperature Monitoring
Monitor:
- Basking surface
- Warm-side ambient
- Cool retreat
- Night-time minimum
An infrared thermometer is useful for checking surface temperatures.
Remember:
THERMOSTAT SETTING ≠ ACTUAL ENCLOSURE TEMPERATURE.
Seasonal Variation
Mozambique Spitting Cobras experience seasonal environmental variation.
Captive husbandry may incorporate modest changes in:
- Day length
- Night temperature
- Humidity
- Feeding response
- Activity
Extreme seasonal cooling is inappropriate.
Humidity
A broad general range of approximately:
40–60% RELATIVE HUMIDITY
is suitable for many individuals.
Normal fluctuations are beneficial.
Some localities experience distinct wet and dry seasons, so permanently maintaining one exact humidity percentage is unnecessary.
Humidity Gradient
Provide:
- Drier basking zone
- Moderate general humidity
- Localised humid retreat
- Fresh drinking water
This allows the snake to regulate moisture exposure.
Humid Retreat
A humid retreat is particularly useful during shedding.
Suitable material can include:
- Slightly damp sphagnum
- Damp soil
- Moist coco-based substrate
It should be:
DAMP — NOT SATURATED.
Avoid Excessive Dampness
Persistently wet substrate can contribute to:
- Dermatitis
- Scale inflammation
- Bacterial growth
- Fungal growth
- Respiratory problems
This species should not be maintained like a permanently humid forest cobra.
Ventilation
Good ventilation is essential.
The goal is:
WARM + MODERATE HUMIDITY + GOOD AIRFLOW.
Misting
Routine heavy misting is generally unnecessary.
Occasional light misting may be useful for:
- Shedding
- Seasonal humidity changes
- Naturalistic planted areas
Allow surfaces to dry afterwards.
Water & Hydration
Fresh clean drinking water should remain continuously available.
Use a stable bowl that:
- Cannot easily overturn
- Is easy to disinfect
- Can be safely serviced
- Is appropriately sized
Some individuals may occasionally soak.
Replace contaminated water promptly.
Substrate
Suitable substrate options include:
- Soil-based savannah mixtures
- Topsoil/sand blends
- Dry coco/soil combinations
- Cypress-type mulch in more humid setups
- Leaf litter
- Appropriate combinations
The substrate should:
- Provide traction
- Retain modest moisture
- Remain low-dust
- Avoid waterlogging
- Permit normal surface movement
Substrate Depth
Approximately:
2–4 in (5–10 cm)
is useful for many naturalistic setups.
Deeper areas may be provided where appropriate.
Furnishings
Useful furnishings include:
- Cork bark
- Broad logs
- Stable rocks
- Low branches
- Artificial vegetation
- Visual barriers
- Multiple hides
Provide both:
OPEN MOVEMENT SPACE
and:
SECURE COVER.
Hides
Provide at least:
- Warm-side hide
- Cool-side hide
- Additional shaded retreat
A humid retreat should also be available when required.
The snake should not have to choose between:
SECURITY
and:
CORRECT TEMPERATURE.
Lighting
Provide a clear day/night cycle.
Approximately:
11–13 HOURS OF DAYLIGHT
is appropriate through much of the year.
A daylight LED can provide:
- Circadian cues
- Bright visible illumination
- Naturalistic light gradients
- Plant support where used
The enclosure should become genuinely dark at night.
Avoid visible:
- Red
- Blue
- Purple
night lamps.
UVB
Mozambique Spitting Cobras naturally move between:
- Open ground
- Scrub
- Burrows
- Vegetation
- Rocky cover
Low-to-moderate UVB may therefore be provided as part of comprehensive modern husbandry.
The principle is:
LOW-TO-MODERATE UVB + SHADE + COMPLETE UV RETREAT.
Target UVI
A practical accessible target is approximately:
UVI 1.0–2.0
in an illuminated area.
Elsewhere provide:
LOWER UV → PARTIAL SHADE → DEEP SHADE → COMPLETE UV RETREAT.
Practical UVB Equipment Guidance
A:
LOW-TO-MODERATE OUTPUT LINEAR UVB SYSTEM
can be appropriate.
The exact lamp required depends upon:
- Lamp model
- Reflector
- Distance
- Mesh
- Enclosure height
- Raised furnishings
The objective is:
UVI 1.0–2.0 AT SNAKE BODY HEIGHT
in the illuminated area.
Do not select equipment solely according to lamp percentage.
Understanding UVB Distance
Remember:
CLOSER = GENERALLY MORE UV
FARTHER AWAY = GENERALLY LESS UV
MESH = USUALLY LESS UV
Low branches or raised rocks may place the snake closer to the lamp.
UV Gradient
A useful arrangement is:
ILLUMINATED AREA: Approximately UVI 1.0–2.0
↓
PARTIAL SHADE: Approximately UVI 0.5–1.0
↓
DENSE COVER: Below approximately UVI 0.5
↓
HIDE: Approaching UVI 0
What This Means in Practice
Do not expose the whole enclosure uniformly to UVB.
Provide one controlled illuminated zone.
The snake should be able to:
- Use low-to-moderate UVB
- Move into filtered light
- Enter deep shade
- Avoid UV completely
without losing access to appropriate temperatures.
UV Meter
A suitable UV Index meter provides the most reliable measurement.
Measure:
AT THE HEIGHT THE SNAKE CAN ACTUALLY REACH.
If You Do Not Have a UV Meter
Use:
- A reputable low-to-moderate-output linear UVB system
- Manufacturer’s current distance guidance
- Correct reflector
- Mesh guidance
- Extensive shaded areas
Do not compensate for uncertainty by installing an excessively powerful lamp.
Heat, UVB & Visible Light
These provide different environmental functions:
HEATING SYSTEM = TEMPERATURE
UVB SYSTEM = ULTRAVIOLET
DAYLIGHT LED = VISIBLE LIGHT
One does not replace another.
Feeding
Mozambique Spitting Cobras are opportunistic predators.
Natural prey can include:
- Rodents
- Other small mammals
- Frogs
- Lizards
- Snakes
- Birds
- Other suitable vertebrates
Captive adults can generally be maintained successfully on appropriately sized whole rodents.
Frozen-Thawed Prey
Where accepted:
APPROPRIATELY PREPARED FROZEN-THAWED PREY
is preferable to routine live vertebrate feeding.
Live rodents can cause serious injury.
Whole-Prey Nutrition
Whole prey provides:
- Muscle
- Bone
- Organs
- Fat
- Micronutrients
Pieces of meat are not an appropriate complete diet.
Prey Size
Use moderate prey appropriate to:
- Age
- Length
- Girth
- Body condition
Avoid unnecessarily oversized meals.
Feeding Frequency
Hatchlings & Small Juveniles
Approximately:
every 5–7 days
depending upon prey size and growth.
Larger Juveniles
Approximately:
every 7–10 days.
Subadults
Approximately:
every 10–14 days.
Adults
Many adults can be maintained on an appropriately sized meal approximately:
every 10–14 days
or somewhat less frequently depending upon:
- Prey size
- Activity
- Sex
- Reproductive condition
- Body condition
Body Condition
A healthy Mozambique Spitting Cobra should appear:
LEAN + MUSCULAR + WELL CONDITIONED.
Monitor:
- Body contour
- Weight trends
- Muscle tone
- Activity
- Feeding history
Obesity
Captive cobras can become overweight if fed too heavily.
Chronic overfeeding may contribute to:
- Reduced activity
- Excessive fat deposition
- Organ disease
- Reproductive problems
- Reduced longevity
Avoid power-feeding juveniles.
Feeding Safety
Food should never be presented directly by hand.
Routine feeding arrangements should minimise unnecessary close exposure.
Because this species can spit defensively, feeding procedures should also account for the possibility of projected venom.
This care sheet deliberately does not provide procedural venomous-snake manipulation instructions.
Behaviour & Temperament
Mozambique Spitting Cobras are alert and responsive.
Normal captive behaviour may include:
- Exploration
- Basking
- Moving between hides
- Investigating environmental changes
- Crepuscular activity
- Nocturnal activity
- Defensive hooding
- Retreating into cover
Individual temperament varies considerably.
Hooding
When threatened, an individual may:
- Raise the anterior body
- Expand the neck into a hood
- Orient toward the perceived threat
Hooding is defensive behaviour.
It should not be deliberately provoked for:
- Photographs
- Videos
- Entertainment
- Routine observation
Spitting Behaviour
Venom projection is also defensive behaviour.
An individual may direct venom toward:
- Eyes
- Face
- Moving objects perceived as threatening
A cobra does not need to be physically touched before spitting.
Do not deliberately provoke this response.
Defensive Behaviour
When threatened, an individual may:
- Attempt to retreat
- Hood
- Project venom
- Reorient
- Strike
- Move rapidly
Not every animal will display every behaviour.
A cobra can bite without hooding or spitting first.
Handling
Mozambique Spitting Cobras should not be casually handled.
This care sheet deliberately does not provide instructions for:
- Free-handling
- Manual restraint
- Physical manipulation
Practical venomous-reptile competence requires specialist training and experience.
Personal Protective Considerations
Because projected venom creates a specific ocular hazard, appropriate specialist husbandry should include suitable eye protection whenever there is a realistic chance of defensive projection.
This does not replace:
- Secure enclosure design
- Secondary containment
- Experience
- Good husbandry procedures
Protective equipment is an additional layer, not a substitute for safe enclosure design.
Cohabitation
Individual housing is recommended.
This allows accurate monitoring of:
- Feeding
- Weight
- Faeces
- Shedding
- Health
- Behaviour
and simplifies routine husbandry.
Controlled reproductive introductions are different from permanent cohabitation.
Cleaning & Routine Care
Regularly monitor:
- Drinking water
- Faeces
- Urates
- Shed skin
- Substrate
- Humidity
- Ventilation
- Temperatures
- Lighting
- Furnishing stability
- Locks
- Parasites
- General behaviour
Spot-clean contamination promptly.
Contaminated Surfaces
Following defensive venom projection, enclosure surfaces, viewing panels or equipment may become contaminated.
Contaminated surfaces should be cleaned appropriately.
Avoid:
- Touching the eyes
- Touching the face
- Handling contaminated equipment carelessly
Wash exposed skin thoroughly after suspected contamination.
Bioactive Enclosures
A naturalistic or bioactive savannah-style setup may be possible for suitably experienced keepers where security remains uncompromised.
However:
BIOACTIVE DOES NOT MEAN MAINTENANCE-FREE.
Continue monitoring:
- Waste
- Substrate condition
- Drainage
- Mould
- Pest species
- Plant health
The ability to reliably locate the snake must remain a priority.
Quarantine
All newly acquired Mozambique Spitting Cobras should undergo strict quarantine.
Approximately:
90 DAYS MINIMUM
is a sensible starting point.
Longer may be appropriate for:
- Imported animals
- Animals of uncertain provenance
- Animals showing clinical abnormalities
- Animals with suspected parasite exposure
Quarantine Setup
A relatively simple secure enclosure makes health monitoring easier.
Provide:
- Simple substrate initially
- Secure hides
- Fresh water
- Appropriate heating
- Limited structural furnishings
- Dedicated equipment
The enclosure should still account for defensive venom projection.
Quarantine Monitoring
Record:
- Body weight
- Feeding
- Defecation
- Urates
- Drinking
- Shedding
- Respiration
- Skin condition
- Mouth condition
- General behaviour
Veterinary examination and parasite screening should be considered where appropriate.
Common Health Concerns
Respiratory Disease
Possible signs include:
- Wheezing
- Clicking
- Nasal discharge
- Excess oral mucus
- Persistent abnormal open-mouth breathing
Potential contributing factors include:
- Incorrect temperatures
- Excessive humidity
- Poor ventilation
Dehydration
Possible signs include:
- Poor sheds
- Reduced body condition
- Abnormal urates
- Sunken appearance
Fresh water should remain continuously available.
Stomatitis
Possible signs include:
- Oral swelling
- Discharge
- Damaged tissue
- Abnormal mouth position
- Reduced feeding
Veterinary assessment is required.
Skin Disease
Persistently damp substrate can contribute to:
- Dermatitis
- Scale inflammation
- Bacterial infection
- Fungal problems
Parasites
Possible signs include:
- Visible mites
- Weight loss
- Poor condition
- Abnormal faeces
- Reduced appetite
Imported animals deserve particularly careful quarantine.
Dysecdysis
Poor shedding may result from:
- Dehydration
- Excessively dry conditions
- Parasites
- Underlying disease
Provide a localised humid retreat where necessary.
Obesity
Maintain a lean, muscular body condition.
Burns
Poorly protected heating equipment can cause serious injury.
Regurgitation
Potential causes include:
- Excessive prey size
- Incorrect temperatures
- Disturbance
- Underlying disease
Repeated regurgitation requires veterinary assessment.
Signs of Good Health
A healthy Mozambique Spitting Cobra should generally display:
- Clear eyes outside shedding
- Clean nostrils
- Quiet respiration
- Intact scales
- Strong muscular body condition
- Appropriate weight
- Normal tongue-flicking
- Confident locomotion
- Appropriate activity
- Normal feeding response
- Normal faeces
- Complete healthy sheds
When to Seek Veterinary Advice
Seek appropriately experienced reptile veterinary care for:
- Respiratory symptoms
- Oral or nasal discharge
- Significant unexplained weight loss
- Persistent abnormal food refusal
- Repeated regurgitation
- Skin lesions
- Burns
- Abnormal swelling
- Persistent abnormal faeces
- Significant injury
- Reproductive problems
- Major unexplained behavioural changes
Veterinary Planning
Suitable veterinary support should be identified before acquisition.
Not every reptile veterinarian is prepared or equipped to work with dangerously venomous spitting cobras.
The veterinary practice should know:
- Exact species
- Venomous status
- Spitting capability
- Approximate size
- Reason for presentation
before transport occurs.
Never unexpectedly arrive at a veterinary practice carrying a venomous snake.
Emergency Planning
A written emergency plan should exist before the animal enters the facility.
It should include:
- Exact species present
- Spitting capability
- Relevant emergency medical arrangements
- Eye-exposure procedures
- Appropriate emergency contacts
- A plan should the primary keeper become incapacitated
- Details of suitably competent backup assistance
Responsible people associated with the premises should know that venomous reptiles are present and know how to summon appropriate assistance without entering the secure reptile area.
Any suspected bite requires:
IMMEDIATE EMERGENCY MEDICAL ASSESSMENT.
Any significant ocular exposure also requires:
IMMEDIATE IRRIGATION + URGENT MEDICAL ASSESSMENT.
Escape Planning
A written escape plan should exist.
An escaped Mozambique Spitting Cobra may seek:
- Dark floor-level recesses
- Boxes
- Shelving
- Furniture
- Warm equipment
- Gaps beneath fixtures
- Low elevated structures
- Dense clutter
Because the species can climb, searches should not be restricted entirely to floor level.
An escaped individual may also spit defensively if approached.
People without appropriate specialist competence should not attempt recovery.
Prevention through secure containment remains the priority.
Breeding
Mozambique Spitting Cobras are:
OVIPAROUS — EGG-LAYING.
Breeding should only be attempted by appropriately experienced venomous-reptile keepers with:
- Mature healthy adults
- Secure facilities
- Appropriate emergency arrangements
- Separate accommodation for offspring
- Legal compliance
- Documented provenance
- A realistic long-term plan for every hatchling
Reproductive Preparation
Breeding animals should be:
- Mature
- Healthy
- Properly conditioned
- Free from significant disease
- Established feeders
Females should possess adequate reserves without being obese.
Seasonal Breeding Cues
Reproductive activity may be influenced by:
- Temperature
- Photoperiod
- Seasonal rainfall patterns
- Feeding
- Locality
Known geographical origin should be retained where available.
Courtship
Breeding activity can involve increased movement and interaction.
Introducing two dangerously venomous snakes increases management complexity considerably.
Controlled reproductive introductions should only occur in specialist facilities designed for this purpose.
Egg-Laying
A gravid female should have access to a secure laying area.
Suitable nesting substrate should:
- Retain moisture
- Remain aerated
- Avoid waterlogging
- Provide privacy
The nest site should be available before the female begins active searching behaviour.
Clutch Size
Approximately:
10–25 EGGS
may occur, with considerable variation between individuals.
Clutch size may be influenced by:
- Female size
- Age
- Condition
- Genetics
- Reproductive history
Breeders should prepare for more hatchlings than expected.
Egg Incubation
A practical incubation range is approximately:
27–29°C (81–84°F).
Maintain:
- Stable temperature
- High but controlled humidity
- Good gas exchange
- Moist but not saturated incubation medium
Avoid overheating.
Incubation commonly lasts approximately:
55–75 DAYS
depending upon temperature and development.
Hatchlings
Hatchlings are:
VENOMOUS FROM HATCHING.
They may also be capable of defensive venom projection from a very young age.
Each requires:
- Secure individual accommodation
- Appropriate thermal gradient
- Suitable humidity
- Fresh water
- Secure hides
- Appropriately sized prey
- Absolute escape prevention
Juvenile containment requires particular care because of their smaller body size.
Hatchling Feeding
Offer appropriately sized whole prey.
The objective is:
RELIABLE FEEDING + STEADY GROWTH + HEALTHY BODY CONDITION.
Avoid power-feeding.
Legal Considerations — Republic of Ireland
The Republic of Ireland is not governed by the UK’s Dangerous Wild Animals Act.
A British Dangerous Wild Animals licence should therefore not be presented as a Republic of Ireland requirement for keeping a Mozambique Spitting Cobra.
However, anyone acquiring, keeping, breeding, transporting, importing, exporting or transferring a dangerously venomous reptile in the Republic of Ireland should verify all legislation and requirements applicable at the time.
Relevant considerations can include:
- Animal health and welfare legislation
- Import and export requirements
- Wildlife-trade restrictions
- Transport requirements
- Public-safety responsibilities
- Property, tenancy and insurance restrictions
- Legal provenance
Always verify the current Republic of Ireland position before acquisition or movement.
Legal Considerations — Northern Ireland
Northern Ireland has its own dangerous wild animal licensing arrangements.
Anyone proposing to keep a Mozambique Spitting Cobra should verify current requirements with the appropriate Northern Ireland authority and obtain any necessary licence before acquisition.
Legal Considerations — Great Britain
In England, Scotland and Wales, cobras fall within the Dangerous Wild Animals licensing framework through their inclusion within the family Elapidae.
Anyone intending to keep a Mozambique Spitting Cobra should verify current requirements with the relevant local authority and obtain any required licence before acquisition.
Important Jurisdiction Distinction
For readers in Ireland and the UK:
REPUBLIC OF IRELAND ≠ NORTHERN IRELAND ≠ GREAT BRITAIN
Their legal frameworks are not interchangeable.
The Dangerous Wild Animals legislation applicable in Great Britain does not apply in the Republic of Ireland.
Northern Ireland operates its own dangerous wild animal licensing arrangements.
Compliance in one jurisdiction does not automatically establish compliance in another.

Common Husbandry Mistakes
Treating a spitting cobra exactly like a non-spitting cobra
Venom projection creates an additional ocular hazard.
No eye-exposure emergency plan
A plan should exist before acquisition.
Waiting to see if ocular symptoms develop before irrigating
Immediate irrigation is important.
Rubbing an eye exposed to venom
This can worsen injury.
Providing an enclosure that is too small
Mozambique Spitting Cobras are active terrestrial snakes.
Providing excessive height but insufficient floor space
Prioritise horizontal movement.
Providing no visual cover
Secure structural complexity is beneficial.
Keeping the whole enclosure too warm
Provide a genuine cool retreat.
Keeping humidity constantly high
This is not a permanently humid rainforest species.
Keeping the enclosure excessively dry
Provide moderate humidity and a humid retreat when required.
Poor ventilation
Fresh airflow is important.
No permanent drinking water
Fresh water should remain continuously available.
Using excessive UVB
Provide measured low-to-moderate exposure.
Providing no UV retreat
Complete shade must always be available.
Choosing UVB solely by percentage
Actual UVI at snake level matters.
Overfeeding
Maintain a lean, muscular body condition.
Power-feeding juveniles
Steady growth is preferable.
Provoking hooding or spitting for photographs or videos
Defensive behaviour should not be deliberately induced.
Assuming the snake must hood or spit before biting
It may strike without either display.
Handling contaminated equipment carelessly
Venom may remain on enclosure surfaces or equipment after defensive projection.
Casual handling
This is a dangerously venomous species.
No secondary containment
The primary enclosure should exist within a secure surrounding facility.
No medical emergency plan
Planning must exist before acquisition.
No escape plan
An escaped animal remains both a bite and venom-projection hazard.
No veterinary plan
Identify suitable veterinary support beforehand.
Breeding without accommodation for hatchlings
Every hatchling is venomous.
Assuming UK DWA legislation applies in the Republic of Ireland
It does not.

Practical UVB Summary
For the Mozambique Spitting Cobra, comprehensive modern husbandry may include:
LOW-TO-MODERATE UVB + BRIGHT DAYLIGHT + STRUCTURAL SHADE + COMPLETE UV RETREAT
A suitable linear UVB system may provide approximately:
UVI 1.0–2.0
at snake body height in an accessible illuminated area.
The exact equipment required depends upon:
- Lamp model
- Reflector
- Distance
- Mesh
- Enclosure construction
- Accessible climbing height
Remember:
CLOSER = GENERALLY MORE UV
FARTHER AWAY = GENERALLY LESS UV
MESH = USUALLY LESS UV
and:
HEAT = TEMPERATURE
UVB = ULTRAVIOLET
DAYLIGHT LED = VISIBLE LIGHT
These perform separate functions.
Because the species can use raised structures, UV exposure should also be checked on low branches or rockwork.
The snake must always be able to choose complete shade.
Important Information
This care sheet provides general husbandry guidance and does not replace species-specific research, specialist practical training, legal advice or veterinary advice. Individual requirements may vary.
The Mozambique Spitting Cobra (Naja mossambica) is a dangerously venomous elapid capable of potentially life-threatening envenomation. It can also project venom defensively toward the eyes, creating an additional risk of serious ocular injury.
Any suspected bite requires immediate emergency medical assessment.
If venom enters the eye, begin immediate irrigation with large quantities of clean water or sterile saline and obtain urgent medical assessment. Do not delay irrigation while looking for specialised solutions.
This care sheet deliberately does not provide step-by-step instructions for handling, restraint or physical manipulation of venomous snakes.
The Dangerous Wild Animals legislation applicable in Great Britain does not apply in the Republic of Ireland. Northern Ireland has separate dangerous wild animal licensing arrangements. Always verify the current requirements for the jurisdiction in which the animal will actually be kept.
Captive-bred animals of documented provenance should be strongly preferred.
If you have concerns about an animal’s health or care, consult a suitably experienced reptile veterinarian who is prepared and equipped to work with dangerously venomous reptiles.
