My Cat is fat and he likes it but im groing concerned about his weight, hes not like regular fat orange tabbys, he can't even jump a fence and he falls down while walking. But its beacause i got him high when he was a bit to young and my dad neuterd him when he was a little baby.But hes a good cat. yet he remind me of hobbes, and a little bit of garfield. how do i get him to stop eating?
