California King Snake (Lampropeltis getula californiae) Care Sheet

​A complete guide for the successful keeping of this active, popular colubrid snake, known for its strong feeding drive and robust temperament.

​1. Overview & Commitment

  • ​Common Name: King Snake, California King Snake (CKS)

  • ​Scientific Name: Lampropeltis getula spp.

  • ​Natural Habitat: Wide variety of habitats across North and Central America. They are primarily terrestrial.

  • ​Size: Moderate, typically reaching 0.9 – 1.5 m (3 – 5 feet) in total length.

  • ​Lifespan: 15 – 25+ years in captivity.

  • ​Temperament: Active, curious, and generally docile once accustomed to handling. They are diurnal/crepuscular.

​:warning: European Union (EU) Legal Note:

The Common King Snake (Lampropeltis getula) and its subspecies, including the California King Snake, are listed under EU Regulations regarding Invasive Alien Species (IAS). This regulation generally prohibits the breeding, sale, exchange, and release of these snakes within member states. Owners should check local and national laws regarding ownership and transport, as regulations vary, but are typically very strict on these species.

​2. Vivarium/Enclosure

​King Snakes require a secure enclosure with adequate floor space for exploration.

  • ​Minimum Adult Enclosure: 90 x 45 x 45 cm (36 x 18 x 18 inches) or a 40-gallon breeder tank equivalent. Security is paramount, as they are known escape artists.

  • ​Structure: Provide multiple hides (minimum two—warm and cool), cork bark, and small climbing branches or rocks for enrichment.

  • ​Burrowing: Provide a deep layer of loose substrate for natural burrowing behavior.

​3. Substrate

​The substrate should facilitate burrowing and maintain relatively dry conditions.

  • ​Recommended Substrate: Aspen shavings (excellent for burrowing and dry), Cypress Mulch, or coconut fiber (coir).

  • ​Management: Keep the substrate relatively dry.

​4. Heating & Temperature

​King Snakes require a consistent thermal gradient for proper thermoregulation.

  • ​Primary Heat Source: Under-Tank Heating Mat (UTH) or Deep Heat Projector (DHP), connected to a Thermostat.

  • ​Basking Spot/Hot Spot: A surface temperature of 30°C – 32°C (86°F – 90°F).

  • ​Cool Side Ambient: 21°C – 24°C (70°F – 75°F).

  • ​Night Time: Temperatures can safely drop to 18°C – 21°C (65°F – 70°F).

​5. Lighting & UV

  • ​Ambient Light: Low-level LED to establish a clear day/night cycle.

  • ​UVB (Optional): Low-level UVB (e.g., a 5% T5 tube) is considered beneficial for active species.

  • ​Photoperiod: Maintain a consistent 12-hour cycle.

​6. Humidity & Hydration

​King Snakes are tolerant of lower humidity but require moisture during shedding.

  • ​Ambient Humidity: Generally requires a moderate level of 40% – 60%.

  • ​Misting: Mist the enclosure lightly if the snake is preparing to shed, or provide a dedicated humid hide filled with damp sphagnum moss.

  • ​Water Dish: A sturdy water bowl should be available 24/7.

​7. Diet & Feeding

​King Snakes are carnivores with an extremely strong feeding response.

  • ​Staple Diet: Appropriately sized frozen/thawed mice or small rats.

  • ​Feeding Schedule (Adult): Feed every 7–14 days.

  • ​Caution: King Snakes must always be housed alone due to their cannibalistic nature. Use long tongs to present prey and avoid feeding inside the habitat.

​8. Handling & Maintenance

  • ​Handling: They become calm with routine handling but may exhibit defensive musking or tail rattling when young.

  • ​Maintenance: Spot-clean waste immediately. Disinfect and refresh the water dish daily.
