Alright, I know we have some real cat folks out there, and I need help. My middle cat (got 3 altogether), is just falling apart. He is overweight (he weighs about 17 pounds), he's diabetic (he gets insulin 2x a day), he's had megacolon, and he's 12 years old. He is now pooping and vomiting on my carpets! The facts : nothing has changed, same cat food, same water, same cat litter (we have 2 boxes which are scooped out daily), I have one box without a lid so he doesn't feel cramped doing his business, he goes to the vet annually for check-ups or whenever he is sick, and he's an indoor cat. I don't mind the mess when it's on the hardwood floors, but now my son has brown stains on his carpet. The baby walks around, pointing to the floor, going, "Poop...poop". This is getting disgusting and embarrassing. Please send advice.
