Common garter snakes are small, fast, diurnal snakes that are active and engaging to watch, unlike many shy nocturnal species.
They are widespread across North America and come in many regional colour forms.
They have a weak rear-fang saliva that is harmless to humans, and they are semi-aquatic, enjoying water.
Their daytime activity makes them appealing, though their varied diet and faster metabolism set them apart from rodent-only snakes.
Housing
A single adult does well in a 90x45x45cm vivarium with plenty of cover, climbing branches, and a large water area, as they enjoy soaking and swimming.
Use an absorbent substrate kept clean, since frequent meals mean frequent waste.
Provide a basking spot of 28-30C and a cooler side around 21-24C, with low-level UVB beneficial for these diurnal baskers.
Keep humidity moderate and ensure good ventilation to prevent respiratory problems.
Diet
Garter snakes have a varied carnivorous diet of fish, earthworms, and rodents.
Avoid feeding goldfish and other thiaminase-rich fish exclusively, as this causes vitamin B1 deficiency; use thiaminase-free fish or supplement, and offer earthworms and whole prey for balance.
Their fast metabolism means feeding juveniles two to three times weekly and adults roughly twice weekly.
A varied diet is essential to long-term health and prevents nutritional deficiencies.
Health
Garter snakes are prone to vitamin and thiamine deficiencies from poor diets, and to respiratory infections in damp, poorly ventilated setups.
Frequent feeding makes a clean enclosure especially important to prevent bacterial problems.
Feed a varied, balanced diet and supplement where needed.
Maintain good hygiene and ventilation.
Their shorter lifespan and faster metabolism call for attentive feeding and prompt veterinary care for any lethargy or breathing changes.
Temperament
Garter snakes are alert, quick, and curious, often more nervous than rodent-eating colubrids.
Many musk readily when first handled but settle with regular gentle contact.
Their daytime activity makes them rewarding to observe.
They rarely bite, and their mild rear-fang saliva is harmless to most people.
Handle gently and briefly at first, letting the snake move through your hands rather than restraining it tightly.
