Why is it...

hehe! Way to go, Seth! I like to toss things in our water bowl, too! Especially my milk jug rings. I used to tip it over but then ma bought one of those petmate fountains and it's way to heavy to tip! There's a little filter in there I try to scratch out, to no avail. Maybe your ma could try a shallow, very heavy ceramic bowl or something.

My cousin, Jazmin has to scoot her water dish around before she'll drink out of it. None of us intentionaly tip our water bowl over. But Jordan likes to wash his toys before he'll play with them. Our humans don't understand either of these habits.

I like to tip over vases of water with flowers in them. It makes a BIG mess, but I can't help myself. Madeleine scoots her bowl around, splashes water out of it unless it is a very shallow bowl, and drops her toys in the bowl sometimes. She is a hydromaniac.
