I took in a garter snake after our weather in Ohio had become decidedly cold, (frost/snow). I found him when he was tiny, (@ 1/2 the diameter of a normal worm). I wasn't sure if he would have enough time to hibernate and I knew the others in the building would have killed him had I not stepped in. So I took him in. My original intent was to release him once the weather was sufficient, but I am worried that I may have effected his instinct to hunt on his own. Keeping him is not a problem, (I would love to), but I want to do what is best for the snake first. Any advice?
