I didn't know it was illegal to sell Garter snakes in Quebec. You learn something new every day! It would make sense as to why I haven't located any breeders here though :s
I went searching for some Garter Snakes yesterday actually because my parents have ponds and I know they can be found near water. As big as the ponds were, I didn't see any Snakes, I used to find breeding balls there and everything, but I think because of the dogs, the snakes may have moved else where. How do they adapt from wild capture to captivity? I would prefer to have a captive bred snake I think because I can't get the idea that the snake once knew bigger and better things than his tank.
