Caught a Garter snake last week

You just contradicted yourself

Nope. Two different scenarios. I keep my snakes in an non-air-conditioned room where they don't need any additional heat. If I kept them in the main part of the house, they would. It would only be a contradiction if I said the opposite things under the same conditions. You've got to start paying better attention to context.
