Garter snakes usually live about 3-4 years in the wild but live about 6-10 years in captivity. Garter snakes are around 20-300 dollars depending on where you buy them, their size and age.
Garter snakes are one of the easiest snakes to care for in captivity. Their calm temperament, small size, and harmless bite make them the ideal pet.
Garter snakes are cold-blooded (ectothermic), so you’ll need a heat lamp or pad to regulate their body temperature if you would want to keep one as a pet. Choose a water dish that is big enough for the snake to curl up in. Garter snakes need a water dish to both drink and bath in.
You should feed a garter snake at least once a week and you should put the food on a paper towel or in a small bowl. You should feed your garter snake earthworms, crickets, or small pieces of raw chicken.
Garter snakes grow up to 2-3 feet long so you will need a terrarium large enough for it. Garter snakes would prefer a 15 gallon tank that's what would be best for them but don't forget the heat lamp.
A garter snake's water needs to be replaced with fresh water daily; it will help maintain the tank's humidity. You should clean the tank every 3-4 weeks because they do defecate (poop).
So if you want a good pet garter snakes are friendly and cute!
