California Kingsnake
Lampropeltis californiae
A highly robust and adaptable North American colubrid, famous for its bold color patterns and a natural immunity to rattlesnake venom. Ideal for beginners due to its hardiness, though highly food-motivated.

Species description
Geographical Origin and Habitat: A highly adaptable terrestrial snake that inhabits deserts, scrublands, pine forests, grasslands, and suburban areas of the western United States and northern Mexico, particularly California, Nevada, and Arizona. It is active during both daytime and twilight depending on temperatures.
Taxonomy and Genetics: Typically reaching an adult length of 100–120 cm. This species displays a striking natural polymorphism: individuals from the same population can show bold transverse bands (banded morph) or a single continuous line running down the spine (striped morph). Natural colors consist of contrasting bands of black or dark brown and white or cream.
Behavior and Habits: Renowned for its voracious appetite and active foraging behavior. It is strictly ophiophagous, meaning it feeds on other snakes (including venomous rattlesnakes, as it possesses a specialized enzymatic immunity to crotalid venom). They are highly active, alert, and can be flighty or defensive when young.
Morphology: Sexual dimorphism is subtle. Adult females are generally slightly longer and heavier than males of the same age. Males possess a longer, thicker tail base where the hemipenes are housed, which tapers more gradually than in females.
Care, breeding and tankmates
Terrarium Setup: Requires a secure horizontal enclosure of at least 90x45x45 cm for an adult. Use dry, burrowable substrates such as aspen shavings or a dry soil-sand mix. Provide climbing branches, cork flats, and multiple small, tight hiding spots. They are exceptional escape artists; the enclosure must be securely locked.
Lighting and Heating: Provide a thermal gradient with a warm side at 30–32°C using an overhead ceramic heater or heat mat, and a cool side at 22–25°C, regulated by a thermostat. At night, temperatures can drop to 20–22°C. A low-level UVB light (2–5%) is recommended.
Humidity and Hydration: Keep humidity levels low, between 30–50%. Excessive humidity or damp substrate can quickly cause respiratory infections or scale rot. Provide a clean, shallow water dish for drinking, and check it regularly.
Feeding and Supplementation: Highly food-motivated. Feed appropriately sized frozen-thawed mice (pinkies for babies, adult mice for adults) every 7–10 days. Always use long feeding tongs to present food, as they have a strong feeding response and may accidentally bite fingers. Supplement with pure calcium weekly.
Compatibility: Strictly solitary and ophiophagous. Under no circumstances should two kingsnakes be housed together, as they will attempt to cannibalize each other, regardless of size.
Health and Common Diseases: Generally very hardy. During shedding, provide a temporary humid hide filled with damp sphagnum moss to prevent incomplete sheds (stuck shed), which can lead to tail necrosis. Monitor for scale rot if the enclosure becomes damp.

The catalog's scalar value is 200 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 200 cm for this species, recorded as total length (TL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
