Food Bowl Flipping
I've got a weird situation with my cat Dax. He and his brother Goober each have their own plastic food and water bowls, which are about an inch deep and 5 inches across. Goober is very good about keeping his neat and clean, but Dax has recently started to be kind of a pain in the butt. He eats a few bites, walks away, then comes back and paws at the bowl until he flips it over. Of course, this scatters the dry food he has in there and lands the wet food on the wood floor. After he does that, he really chows down and eats everything he spilled. If the food stays in the bowl though, he's not as interested in it unless he's really hungry.
At first I thought maybe he just didn't like the dish-washing liquid I used, so I changed it to another brand, but had no luck. I also tried an experiment where I put some of the food on the floor instead of in the bowl and he went right to it.
My question is, what could be causing this behavior? He's 10 months old and this has been going on for a couple of months. Does he not like the shape of the bowl? I was thinking of trying a flat plate and seeing if that made a difference. It's pretty strange. I obviously don't like him eating off the floor if it can be avoided.
