My 12 year old cat Roscoe has episodes of throwing up his food (up to four times a day & for a couple of days), after he eats. He then will go a week or so without throwing up at all. He still has a appetite after he throws up and goes back to his bowl and eats more...then throws it up right after. I have never seen a hairball in his vomit, but there is loose hair in it. He also has some dark areas in his stool that I assume is blood from his system because of throwing up. His stool sample is normal
All his blood tests come back normal, his xrays are clear, I switched him to feline i/d wet food, tried predisone in case his intestinal track/stomach was inflamed, he has been dewormed, and given antibiotics in case he had a parasite of some kind, I have given him hairball remedy twice a day in his food, and he doesn't not gobble his food. All this, AND none of it has helped. :( I feel so bad for the dude. The vet says the next step is to take him to get his digestive system scoped and biopsied. I am nervous about subjecting him to it since he is older and they weren't even sure they would be able to find anything.
Has anyone else had a cat with these issues, and if so...what ended up being the cause and how did you end up treating him? I don't know what else to do for him. :(
