i am a little confused about the question.... you were told to not touch the mouse because your sent will get on it? who told you this?

i take it you are feeding live, and nature will do it's thing, all you have to do is just watch. mice are only really a threat to a snake if they are left in the tank for long periods of time. are for knocking out the mouse... personally i think it is a little cruel. it's already gonna get the life squeezed out of it it's not really necessary to hit it on the head.

and as for the water bowl... do you watch her 24 hours a day? is he/she peeing or passing urates? how do you know she isn't drinking?
