Burmese Python (Python bivittatus)
The Burmese Python is one of the world’s largest snakes. Although generally calm when appropriately managed, its immense adult size, strength, feeding response and housing requirements make it suitable only for experienced keepers with the space, equipment and procedures required to manage a giant constrictor safely.
This is a long-lived animal requiring a substantial commitment of space, money and time.

Important Commitment & Safety Warning
Burmese Pythons become exceptionally large and powerful.
Before acquiring one, the keeper must realistically consider:
- Permanent adult accommodation
- Heating and electricity costs
- Secure enclosure construction
- Cleaning and waste management
- Access to appropriately sized prey
- Veterinary access
- Safe movement and restraint procedures
- Availability of another competent adult when required
- Long-term care lasting potentially several decades
An adult Burmese Python should never be regarded as a casually handled pet.
Local laws and regulations concerning large constrictors should always be checked before acquisition.
Enclosure Size
There is no single enclosure dimension suitable for every adult Burmese Python because adult size varies considerably.
The enclosure should be large enough for the snake to:
- Fully extend its body
- Turn without restriction
- Move between distinct thermal zones
- Explore
- Use elevated structures where appropriate
- Rest completely within secure hides
- Access water easily
For adults, custom-built accommodation is normally required.
As a practical starting point, an adult enclosure will commonly need to be around:
300 × 120 × 120 cm or larger
Large females may require substantially more space, potentially approaching room-sized accommodation.
Whenever possible, enclosure length should approach or exceed the snake’s total body length.
Juveniles can be maintained in smaller secure enclosures provided appropriate thermal gradients, hides and environmental complexity are maintained.
Enclosure Security
Security is essential.
Adult Burmese Pythons are exceptionally strong and can exploit surprisingly small weaknesses in enclosure construction.
The enclosure should have:
- Strong construction
- Secure locking doors
- Protected ventilation
- Reinforced fixtures
- Guarded heating equipment
- No accessible electrical cables
- No gaps that could permit escape
Large adult accommodation should ideally incorporate a method of safely separating or shifting the snake during cleaning and maintenance.
Furnishing & Enrichment
A large snake still benefits from environmental complexity.
Provide:
- Multiple secure hides
- Visual barriers
- Large cork pieces
- Heavy branches
- Stable platforms
- Different substrate depths and textures
- Opportunities for climbing
- Areas of cover
- Water access
All structures must be capable of safely supporting the animal’s full weight.
Heavy furnishings must be positioned so they cannot collapse onto or trap the snake.
Substrate
Suitable substrates include:
- Cypress mulch
- Orchid bark
- Coconut husk
- Soil-based mixtures
- Other safe moisture-retaining substrates
The substrate should allow normal movement and help maintain appropriate environmental humidity.
The enclosure should not remain constantly wet.
Large adults produce substantial quantities of waste, so ease of cleaning and hygiene must be considered when designing the enclosure.
Temperature
A clear thermal gradient must be available.
Basking / Warm Surface
Approximately:
31–33°C
Warm Ambient Area
Approximately:
27–30°C
Cool Area
Approximately:
23–26°C
A modest nighttime reduction is acceptable provided the animal continues to have access to suitable temperatures and is not subjected to prolonged chilling.
These figures are useful starting points rather than rigid values.
Behaviour, body condition, digestion and enclosure measurements should all be considered.
Heating
Large Burmese Python enclosures often require substantial heating capacity.
Suitable systems may include:
- Radiant heat panels
- Guarded ceramic heat emitters
- Guarded overhead heating
- Appropriately designed combinations of heat sources
Every heat source must be thermostatically controlled.
Heating equipment must also be physically protected so the snake cannot contact hot surfaces or damage electrical equipment.
Surface temperatures should be checked with an infrared thermometer, while ambient temperatures should be monitored using reliable digital thermometers.
Lighting & UVB
Provide a clear day/night cycle.
Approximately 11–13 hours of daylight, with seasonal variation if desired, provides a sensible photoperiod.
Burmese Pythons can survive without artificial UVB when otherwise correctly maintained, but appropriately provided UVB can form part of a high-quality captive environment.
When UVB is provided, approximately:
UVI 2–3 in the primary exposed/basking zone
is a reasonable target, while ensuring the snake can move into:
- Lower UV exposure
- Complete shade
- Dark secure hides
The percentage printed on a UVB lamp does not indicate the UVI reaching the animal.
Actual exposure depends on:
- Lamp type
- Reflector
- Distance
- Mesh or screening
- Installation
- Lamp age
A suitable UV meter provides the most reliable way to assess exposure.
All lighting should be inaccessible to the snake or securely guarded.
Humidity
A general ambient humidity around:
55–70%
is a useful starting range.
Temporary increases may occur naturally and can be useful during shedding.
Humidity should not be maintained by keeping the enclosure permanently wet.
The objective is:
Appropriate humidity + ventilation + dry resting surfaces
Persistent wetness and stagnant air can contribute to skin and respiratory problems.
Water
Fresh drinking water must always be available.
Burmese Pythons are capable swimmers and many individuals will voluntarily soak.
Where practical, providing a sufficiently large, stable water area for soaking can be valuable enrichment, particularly in very large purpose-built enclosures.
However, water provision must be designed around:
- Hygiene
- Safe access
- Ease of drainage
- Ease of cleaning
- Prevention of flooding
- The size and strength of the animal
Water should be changed whenever contaminated.
Large integrated pools should ideally incorporate convenient drainage because manually emptying large volumes of contaminated water rapidly becomes impractical.
Hides
Provide at least two secure resting areas positioned across the thermal gradient.
Hides should allow the snake to feel enclosed rather than exposed.
For very large adults, hides may take the form of:
- Large boxes
- Covered platforms
- Built-in retreats
- Partially enclosed sections of the enclosure
A giant snake still requires somewhere secure to retreat.
Feeding
Burmese Pythons consume a variety of vertebrate prey.
Suitable captive foods include appropriately sized:
- Rats
- Rabbits
- Poultry
- Other nutritionally appropriate whole vertebrate prey
Frozen-thawed prey is preferred wherever practical.
Routine live feeding creates unnecessary injury risk and should be avoided.
Whole prey generally provides complete nutrition, so routine vitamin or mineral supplementation is unnecessary for healthy animals consuming an appropriate varied whole-prey diet.
Feeding Frequency
Feeding should be based on:
- Age
- Size
- Prey size
- Growth
- Activity
- Reproductive condition
- Body condition
Young growing snakes require more frequent meals than adults.
Adults commonly require feeding only every 2–4 weeks, and large mature animals may require longer intervals depending on meal size and body condition.
Avoid attempting to produce maximum growth.
Burmese Pythons have extremely efficient metabolisms and readily become obese in captivity.
Prey Size
Do not rely solely on the old rule of choosing prey according to the widest part of the snake’s body.
For large constrictors, prey selection should consider:
- Snake size
- Body condition
- Age
- Feeding frequency
- Prey species
- Individual metabolism
Moderate meals are preferable to routinely offering enormous prey.
Obesity
Obesity is one of the most important captive health concerns in giant constrictors.
Signs of excessive body condition may include:
- Excessively rounded body shape
- Deep skin folds
- Poor muscle definition
- Large fatty deposits
- Reduced activity
- Difficulty moving normally
A healthy Burmese Python should be powerful and muscular rather than excessively heavy.
Regular weight records and photographs can help monitor long-term condition.
Feeding Safety
A large Burmese Python can develop an extremely powerful feeding response.
Use:
- Long feeding tongs
- Consistent feeding procedures
- Secure enclosure access
- Appropriate protective barriers where necessary
Avoid placing hands near the head of a food-responsive animal.
For very large individuals, another competent adult should be available whenever the planned procedure presents a realistic risk that one person could not safely manage.
Feeding procedures should be designed around the individual snake and enclosure rather than relying on simplistic universal handler-to-snake-length formulas.
Handling
Juveniles can generally become accustomed to calm routine interaction.
Large adults require considerably greater caution.
Handling should never be used merely to demonstrate control over the animal.
For large individuals:
- Plan the interaction beforehand
- Avoid handling immediately after feeding
- Avoid handling during an intense feeding response
- Keep the head under observation
- Ensure assistance is available when appropriate
- Use hooks, barriers and shift areas where useful
The larger the snake becomes, the more routine husbandry should rely on safe enclosure design and cooperative movement rather than physical restraint.
Temperament
Many Burmese Pythons are relatively calm animals, but temperament varies between individuals.
Defensive behaviour may include:
- Hissing
- Striking
- Rapid withdrawal
- Musking in younger animals
A calm Burmese Python remains an extremely powerful animal.
Docility should never be confused with an absence of risk.
Shedding
A healthy shed should normally come away largely intact.
During the shedding cycle:
- Ensure appropriate humidity
- Provide access to fresh water
- Provide textured surfaces
- Avoid unnecessary handling
Persistent retained shed can indicate problems with:
- Hydration
- Humidity
- Temperature
- Health
- Previous husbandry
Routine forced bathing should not be necessary in a correctly maintained animal.
Cleaning
Spot-clean waste as soon as possible.
Because adults produce very large quantities of urine and faeces, enclosure design should prioritise practical sanitation.
Regularly clean:
- Water containers
- Feeding areas
- Soiled substrate
- Frequently contacted surfaces
Perform deeper cleaning as required without unnecessarily stripping a clean enclosure on an arbitrary schedule.
Quarantine
New snakes should be quarantined away from established reptiles.
During quarantine monitor:
- Appetite
- Body weight
- Faeces
- Shedding
- Respiration
- Behaviour
- External parasites
Use separate equipment wherever practical.
Veterinary faecal examination may be appropriate, particularly for animals with uncertain histories.
Common Health Concerns
Potential health problems include:
- Obesity
- Respiratory disease
- Mites
- Internal parasites
- Mouth disease
- Retained shed
- Scale and skin infections
- Thermal burns
- Regurgitation
- Reproductive complications
- Trauma associated with inappropriate live prey
Seek an experienced reptile veterinarian if abnormalities persist or the animal’s condition deteriorates.
Respiratory Disease
Possible signs include:
- Open-mouth breathing
- Wheezing
- Clicking
- Excess mucus
- Nasal discharge
- Abnormal head positioning
- Reduced activity
- Loss of appetite
Respiratory disease can be associated with inappropriate temperature, poor ventilation, persistently wet conditions or infectious disease.
Veterinary assessment is recommended.
Breeding
Burmese Pythons are oviparous.
Breeding should only be attempted by experienced keepers who have:
- Suitable adult accommodation
- Space for offspring
- Safe introduction/separation procedures
- Incubation equipment
- Appropriate veterinary support
- Realistic plans for placing large numbers of offspring
Females can produce very large clutches.
Clutches commonly contain approximately 20–60 eggs, although considerably larger clutches have been documented.
Maternal Incubation
Female Burmese Pythons display remarkable maternal behaviour.
A female may coil around her clutch and produce muscular contractions that help maintain elevated egg temperatures.
In captivity, eggs may either be maternally incubated under carefully controlled conditions or artificially incubated.
The female should not be unnecessarily disturbed when maternal incubation is being used.
Artificial Incubation
Eggs are commonly incubated at approximately:
30–32°C
Incubation frequently lasts around:
55–70 days
with variation according to temperature and other conditions.
Eggs should not be routinely rotated after laying.
Incubation substrate should maintain appropriate moisture without leaving the eggs sitting in free water.
Hatchlings
Hatchlings should be housed securely and individually.
Provide:
- Appropriate thermal gradient
- Multiple secure hides
- Fresh water
- Suitable humidity
- Appropriately sized whole prey
Do not deliberately power-feed hatchlings for maximum growth.
Controlled, steady development is preferable.
Lifespan & Long-Term Commitment
Burmese Pythons can live for 20 years or considerably longer.
An animal purchased as a manageable juvenile can become an enormous adult requiring specialist accommodation and handling procedures.
The adult requirements should therefore be planned before the animal is acquired, not after it outgrows conventional housing.
Final Husbandry Principles
Successful Burmese Python husbandry depends on:
- Exceptional enclosure security
- Sufficient usable space
- A genuine thermal gradient
- Appropriate humidity without persistent wetness
- Fresh water
- Environmental complexity
- Moderate whole-prey feeding
- Prevention of obesity
- Safe keeper procedures
- Long-term planning
- Experienced veterinary care when required
Their impressive appearance and often calm temperament should never obscure the reality that Python bivittatus is a giant constrictor requiring specialist lifelong management.
