There could be several things that is causing your cat to vomit. Some of the more common things that cause vomiting and anorexia in a cat are gastritis (inflammation of the stomach wall), pancreatitis, intestinal parasites, and irritable bowel disease. I would withhold food from your cat for about 24 hours to give the stomach some time to rest. If she is continuing to vomit or still not eating after this, then I would recommend taking her in to see your vet. They can give her nausea medication and fluids if she is dehydrated. They may also recommend blood work and X-rays if it is indicated. Good luck.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Baby!

    Causes of vomiting and diarrhea in cats are: intestinal parasites, viral or bacterial infections, she ate something gross that is upsetting her stomach, pancreatitis, food allergy or intolerance, new treat or table food.

    She likely is reacting to the food, despite being on it at the shelter or has worms or has a virus. Sadly with cats there is not much to do at home because they can not safely receive human medications. I would pull up her food and fast her for 12 hours. Then try to feed her again. If she continues to not eat, vomit and have diarrhea she should be seen by a Vet.

    I hope this helps and I wish Baby a speedy recovery!

    She might have eaten something spoiled that is causing this. withhold food for 8 hours then offer Sookie boiled boneless chicken and rice every 6 hours in small portions. if she is eating and not vomiting, continue with this diet for 2 days.

    After 2 days, you can put her back gradually on her normal food. If she continues vomiting or is not eating, take her to the vet to get treatment.

    Best recommendation is to withdraw food for 12-24 hours. If the vomiting stops, resume feeding her normal cat food in smaller, more frequent meals. If the vomiting does not stop, beat recommendation is to have her evaluated by a veterinarian. She may be getting dehydrated and your vet may want to do some diagnostic testing. She may also benefit from medications to stop the vomiting. Cats can vomit for lots of reasons, such as organ dysfunction, gastrointestinal problems, or foreign bodies. Sometimes cats can vomit for (what seems like) no reason at all. It's important to rule out the more serious causes.

    Vomiting can be a result of something minor, like a cat consuming her meal too quickly, or it can be a sign of a much more serious condition that requires immediate medical attention. Usually, a cat vomits because she ate something disagreeable, ate too much, or played too soon after dinner. Vomiting can also be associated with gastrointestinal or systemic disorders, or foreign bodies. Since your cat has been vomiting for a week, I would be concerned that her vomiting is more likely due to a GI or systemic disorder, or a foreign body. I would recommend taking her into your vet to be checked out as soon as possible.
