My cousins cat seems different, we are worried he is sick, does anyone know anything about his symptoms?
He is 8 years old, has always been fat, good appetite, but very active and playful. He has lost a lot of weight, hissing at people and the other cats. His appetite is now up and down, sleeping a lot. White gums. Attacking the dogs through the window(something he has never done before). My cousin is terrified too take him to the vet. So does anyone know what's wrong with him???
