Care Guide for California Rat Snakes


Temperature and Humidity

California Rat Snakes are ectothermic animals and rely on external heat sources to regulate their body temperature. Maintaining a proper temperature gradient in the enclosure is crucial. The warm side of the tank should be around 85-90°F (29-32°C), while the cool side should be maintained at around 70-75°F (21-24°C). Using an under-tank heating pad or a heat lamp can help achieve these temperature ranges.

The humidity level in the enclosure should be kept between 40-60%. This can be achieved by misting the enclosure with water or by using a reptile humidifier. Providing a water bowl for drinking and soaking is also important to ensure proper hydration.



Handling and Enrichment

Enrichment is also important for the overall well-being of the snake. Providing hiding spots, branches, and climbing structures in the enclosure can help simulate their natural environment and provide mental stimulation.

By following these care guidelines, you can ensure a happy and healthy life for your California Rat Snake. Remember to do thorough research and consult with experienced reptile keepers or herpetologists for any specific care requirements.

Breeding California Rat Snakes

Mating Season


Once the snakes have been introduced, it is recommended to closely monitor their behavior. Mating behavior may include males following and gently biting the females, as well as a twisting or coiling motion during copulation. If successful mating occurs, the female will lay a clutch of eggs within a few weeks.

Egg Incubation

Egg Incubation

The incubation period for California Rat Snake eggs is typically around 55 to 65 days. During this time, it is vital to regularly monitor the temperature and humidity levels to ensure they remain within the optimal range. After the incubation period, the eggs will start to hatch, and you can expect a clutch of healthy baby snakes.
