cat help

My domestic long hair has had some blood in his stools, he eats like a horse, and he's been lethargic in his behavior?? It just recently started when we moved his litter pan. He's not a big cat and his stools have always been Hugh?? We sometimes used to feed him small amounts of table food, but we stopped that several weeks ago. Suggestions?? Thank you

If your cat is lethargic, I would suggest a vet visit. Bring a stool sample with you. Does your cat go outdoors? It could be something as simple as worms or something more serious. Blood and lethargy = vet visit.
