- Care level
- Beginner-friendly
- Lifespan
- 10 years or more
- Size
- About 55cm on average (max 137cm)
- Temperature
- Humidity
- 35〜60%
- Diet
- Frozen-thawed mice, fish, earthworms, amphibians
- Temperature & Humidity
- Keep the basking surface at 29-32 C and the cool side at 23-27 C, dropping to 18-24 C at night. Cool-side air temperatures above 33 C are dangerous. Aim for 35-60% humidity, measured with a digital hygrometer probe placed in the middle of the enclosure.
- Enclosure
- Active climbers and swimmers, so allow at least 120 x 60 x 60 cm for a single adult. Provide a substrate layer at least 5 cm deep, topped with leaf litter to hold humidity and encourage exploration. A water container large enough for the whole snake to soak in should always be available.
- Diet & Feeding
- In the wild it eats fish, amphibians and earthworms. In captivity the staple should be appropriately sized frozen-thawed mice; a diet of fish alone can cause thiamine deficiency.
- Temperament
- Placid and tolerant of handling, though a startled snake will release a foul-smelling secretion from its cloaca. Its venom is very weak and a bite poses no danger to people.
- Notes
- Not listed on any CITES appendix, and not among the designated dangerous animals in the Japanese Act on Welfare and Management of Animals. One of the few snakes that can be kept in groups, but feed individuals separately to avoid accidents.

The Common Garter Snake is a small-to-medium North American snake with bold yellow stripes, widely kept as a beginner-friendly starter species.
7 things to know before welcoming a Common Garter Snake
1Enclosure Size
Adults average around 55cm but can reach up to 137cm, so provide an enclosure large enough for the snake to stretch out fully. Because individual growth varies, plan to reassess enclosure size as your snake matures.
2Temperature & Humidity
As with most pet snakes, maintaining a temperature gradient in the enclosure (a warm side and a cool side) is fundamental to their well-being. Keep humidity from dropping too low, as this can lead to incomplete shedding, and provide a water dish while monitoring conditions regularly.
3Docile, Easy-to-Handle Temperament
They generally have a calm temperament and, once accustomed to handling, can be quite docile. That said, wild-caught or unaccustomed individuals may hiss or release musk as a defensive response when startled.
4Group Housing
The Common Garter Snake is one of the few snake species hardy enough to be kept in small groups within the same enclosure. That said, when housing multiple individuals together, it's essential to monitor each snake's feeding and health closely.
5Diet & Feeding Notes
Their dietary preferences can differ from those of many common pet snakes, so it's worth confirming the appropriate food type and feeding frequency for your specific snake before bringing one home. Feeding response can vary between individuals.
6Escape Prevention
They are slender and quick-moving, so choose an enclosure with a secure, well-fitted lid or lock. Even small gaps can allow an escape, so make it a habit to regularly inspect the entire setup.
7Long-Term Commitment
With a lifespan of 10 years or more, it's important to consider in advance whether you can provide care over the long term before bringing one home. Plan ahead for life changes such as travel or moving.
