Our question this week was:

We have a small white cat about 6-years-old. He vomits all the time and he will spray areas with blood and pee blood and he constantly has diarrhea. He has been to the vet several times, he says he must eat outdoor things. This has been going on for about 2 years now, the cat is always irritable and wants to eat all the time.

Answer

Hi – thanks for your email Vicky. To be honest – your email does not make complete sense to me. I know it can be difficult to communicate everything in writing. You wrote that your 6-year-old cat vomits, has diarrhea, urinates bloody urine, wants to eat all the time and your vet says he must eat outdoor things. I have no idea what that means.

If your cat vomits and has blood in the urine – there is some physical medical problem. He may have bladder stones, a urinary tract infection or bladder inflammation (commonly called Feline Interstitial Cystitis [FIC]).

I would recommend that he have a urinalysis done, an x-ray of his abdomen to help determine if there are bladder stones and routine blood work (a complete blood count [CBC], biochemical profile, and feline leukemia virus [FeLV] and feline immunodeficiency virus [FIV] testing.

There are lots of causes for vomiting and diarrhea. For more information on these causes – go to Vomiting in Cats and Diarrhea in Cats. These problems may be related to the urinary problem or caused by something different. It is hard to determine this without some tests.

There is some underlying cause – it is a matter of finding it. In the meantime, I'd recommend that you ensure your cat is indoors only, eating a good quality premium cat food for adult cats and has PLENTY of fresh clean water. Encourage him to drink

I'd recommend that you read the links in this answer to give you more information on some of the many different possible causes of his problems.

Best of luck!
