Good luck. I have a cat (Juni Rose) and she cannot pass by a glass with liquid in it without tipping it over. She does it with empty glasses too, but the most messy tipping events are the ones I remember. I think it may be a game for them

I would buy a large, heavy, ceramic, flat bottomed bowl or even a quiche dish would do.

My bunnies like to tip their bowls too.

P-E-T-S!
