thats no joke.. my wife used to have a cat that was only a little bigger than average.. and it could lay down a pile bigger than most people at times.
Ewwwwww. I've seen dogs, even little ones, do that, but not cats!
I'm allergic to cats, but a friend of mine had 3, 2 average size and one big cat. He wasn't exactly fat, just big. She had at least 4 litter boxes and seemed to be constantly cleaning one or the other. And replacing air fresheners in every room. (They didn't help.)
