My 9-month-old cat is vomiting bile and not eating. Should I worry?

The most common reason for symptoms you are describing in a young cat is an intestinal obstruction. Young cats often eat things they shouldn't (like hair ties, rubber door stop ends, strings, etc). I suggest you have him examined by your vet. This can be very serious. ( http://www.petcoach.co/article/foreign-bodies-in-the-small-intestine-of-cats/ )

It sounds as Jixie 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 him to the vet the first chance you get as it does sound serious, 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.

Acute vomiting and diarrhea, especially with poor appetite and lethargy, are certainly cause for concern. This could be caused by an infection, something stuck in Max's intestines, or a metabolic problem. At the veterinarian, they will examine him and probably take x-rays and run some lab work to look for the underlying cause of Max's issues. I wouldn't wait very long to go to the vet since Max is so young and small and so can become dehydrated quickly. See if you can get in for an exam today.

That's definitely concerning. Bombay could have something stuck in his intestines, an intestinal parasite, or even a metabolic problem. I would recommend getting him to the clinic this week for an exam and some x-rays to see if they can find a cause. He could also have vomited once because of eating something strange or a virus, and the vomiting itself irritated his stomach so he keeps vomiting - sometime treatment with fluids and an anti-vomiting medication is all that is needed to settle these guys down, but it's important to do testing first to make sure nothing else is going on. Good luck!

Poor Splash! This vomiting could be caused by a GI illness, eating something rotten, a foreign body, or pancreatitis. Given that he has been vomiting since Friday morning, it's time to see a vet as soon as possible. The vet can diagnose what is causing the vomiting so he can be treated . I would take Splash into a vet now.

Poor Willie! Given that it appears she has vomited a foreign object (decorative balls from your bedspread) and the face she isn't eating, I would take her into a vet now. It's actually very serious when a cat doesn't eat, as they will develop a fatty liver when they go too long without eating. A fatty liver is fatal without treatment, so that needs to be avoided. She may need x-rays to determine if she has any more of those balls in her GI tract. Please take her into a vet now. Best of luck, I hope this helps!

Oh dear - poor Mickey! I agree that it's very concerning that she's been vomiting so much today and hasn't been eating or drinking. It's less surprising to me that she isn't using the litter box right now -- remember, nothing going in means nothing coming out. Given her young age, the most common cause for vomiting with a loss of appetite is a gastrointestinal obstruction or blockage from eating something she shouldn't have. As a result, I would strongly recommend taking Mickey to an emergency vet right away for evaluation. They'll be able to examine her and perform any necessary diagnostics (namely x-rays) to help get to the bottom of this issue. If Mickey is diagnosed with an obstruction, she'll need surgery to remove the blockage. In this situation, it's best not to delay treatment. I hope that she makes a speedy recovery!
