My cat has always been a big eater but it seems to be getting out of control. In the past I would try to buy expensive healthy diet cat food and he would REFUSE to eat it. Then he would destroy my house. So I took him back to the cheapy food which he seems to prefer. Lately hes been eating even more and when he poops it look like a cow patty. One poop in the litter box and it has to be changed! Is this normal? His pile can be 5 or 6 inches across! Also he starts meowing like crazy if he can even see the bottle of his bowl. He will wake you up at night if his food bowl gets empty while we’re sleeping. Its getting to be a little much and Ive thought he has a eating disorder!
