There are a couple of things you can do for moving water, and food dishes.

1) Rubbermaid has a shelf mat that you can cut to size, and put it under the dish, won't move.

2) Buy a dog dish that has a rubberized bottom.

or

3) Go to your local hardware store and buy some weatherstripping. I was told of this when Yoshi was a baby and started *moving* things around (breaking too ) It just takes a tiny little ball of it, place it on the bottom and it will NOT move. But, it will come up with some force. I put this on all my breakable items so that when Yoshi got up on the counter's he wasn't susposed to be on, my things were safe from him knocking them down!

So what is worse, walking into a water dish or stepping on a hairball in the middle of the night??!!
