My cat has blood & mucus coming from his stool - more blood than stool. As well as he has blood in his mucus when he sneezes. He is lethargic, moody, becoming aggressive, his fur has gone from silky to ruff, he isn't eating even 1/2 as much as he once did & he sleeps up to 18hrs without moving.
What can possibly b wrong & is it a death sentence?
