Thanks Nate, I think I will try that as to be honest even if we are in all day I have never seen them go for water. In our area however, the water isnt that great and can sometimes taste irony so it could be that its really hard to tell. At the moment we dont even see our chipmunks, dont know if the two girls are hibernating inside but they wont come out of their beds and their food is never touched, just getting a bit over cautious probably.
