Why is my 7-month-old kitten throwing up water and not eating?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 7 months and 15 days old

I have a seven month old kitten. He's not gotten his vaccines or been tested yet. He's been throwing up since sometime after 0300 this morning. I didn't know it was him, as I have an older cat who has done this before, but it's never been a problem. However, I just came home -- it's 2117 -- and found one more throw up spot. Then, as I was cleaning up, I saw him throw up again, this time just water. He's refused to eat tonight. Do you have any advice or thoughts on what this could be?

It sounds as your pet is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking Guinness to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

    There are a couple of things that could be causing Guinness to throw up such as a severe GI illness, eating something rotten, a foreign body, or pancreatitis. I can tell you it's really serious when a cat refuses to eat, as they will develop a fatty liver if they do without eating for too long. I would take him into a vet asap. Best of luck.
