I only have one female that likes to tip them, and then that's really rare. I've tried a lot of different bowls and the plastic crock dog bowls work the best for me. Ceramics are heavy and NEVER tip but they drive me nuts. They're heavy and are a guaranteed smash if they drop. I ordered 20 of them once and had to return them all cause they weren't sealed properly and leaked all over all the cages. :O I wasn't happy, lol.
