My cat isn't eating and has vomited several times. What's wrong?

This is very concerning and very abnormal. Vomiting in cats can be caused by primary issues with the gastrointestinal tract, dysfunction of the organs, infection, intolerance to a diet, etc. Either way, this is very concerning and KitKat should be seen by a veterinarian ASAP for examination and potential diagnostics.

It sounds like your cat is having some issues which could be related to the Vietnamese food you fed it last night or cats can get something call triaditis which is inflammation of the pancreas, liver, and small intestine and gallbladder. Because of the frequency of vomiting and the likelihood that its blood that you're seeing in the vomit I recommend your cat see a veterinarian as soon as possible.

It sounds as Sia 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 her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

Hi. Unfortunately, there are many possibilities let causes of vomiting and not eating. This can range from something they ate upsetting the tummy, toxins, parasites, or even a foreign object in the GI tract that he swollen that could be stuck. The last one we get very suspicious of in young kitties. I would highly recommend getting Bart in to the ER this evening.

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 Marylin 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 her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

Since it sounds like KD never skips a meal, its possible he is getting sick. Just like people, there are many conditions that can make pets feel sick. This could range from bacterial over growth to intestinal blockage. Also like us, diseases are best addressed early and this may result in a better prognosis. I recommend to have him examined by the veterinarian if he is not eating for 24 hours, not drinking well or if he is getting worse. The doctor will need to learn the underlying cause in order to give appropriate treatment. Bring in a stool sample in case the doctor needs to test it. I hope KD starts feeling better quickly! Please feel free to post any additional questions!
