Common causes of vomiting in cats includes hairballs, food allergy, eating too fast, GI blockage, intestinal parasites, IBD, intestinal lymphoma, hyperthyroidism, systemic disease (liver, kidney, pancreas, diabetes), among others. You can remove her food and wait 6-12 hours to see if the vomiting stops. Then only give her small amounts of her food. If the vomiting continues tomorrow, Mochi should get checked out by her vet.

Poor Lila! This intermittent vomiting could be caused by an ulcer, gastritis, foreign body, heartworm disease, feline panleukopenia, or inner ear disease among many other causes. I would recommend taking Lila into the vet for an exam. The vet can do a physical exam, routine blood tests, a urinalysis, and any other tests that they deem necessary in order to diagnose what is causing her symptoms. Once a cause is found, the vet can institute an appropriate treatment.

It sounds as Lily 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.

Why is my cat throwing up yellow bile? What does it mean and what to do?

There could be several causes of vomiting in your cat - gastritis (inflammation of the stomach wall), pancreatitis, inflammatory bowel disease, intestinal parasites. The vomitus is yellow because it is mostly stomach acid and bile. This is not unusual if the stomach is empty of food when the cat vomits. I would recommend withholding food for 12-24 hours (small amounts of water is ok) and see if the vomiting resolves. If Toffee continues vomiting then I would recommend you take her in to the vet to be checked out.

My cat stopped eating and vomits. When should I call the vet?

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.

Why is my older cat throwing up whole kibble right after eating?

Poor Sweetie! In older cats, I would be concerned that the vomiting is caused by kidney disease, inflammatory bowel disease, a foreign body, or intestinal lymphoma. I would take her into the vet first thing in the morning. The vet can do a physical exam, routine blood tests, a urinalysis, x-rays, and possibly an ultrasound to determine what is causing her vomiting. Once the cause is found, the vet can recommend a possible treatment.

My cat frequently throws up food and liquid. Hairball or serious?

It's probably something more serious. chronic vomiting can be caused by various conditions (foreign body, pancreatitis, lymphoma, IBD and more...), you will need to take her to the vet in order to get checked and have a blood test done as a first step to try and find out what is causing this.

Why is my adult cat throwing up clear liquid and won't eat?

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.

My cat keeps throwing up food. Is it due to our recent move?

The possible causes of for vomiting are numerous. The fact that you recently moved (be in a month ago at this point) could play a role potentially as stress is a definite cause of GI upset in cats. Other causes can be dietary, gastroenteritis, pancreatitis, kidney / liver disease, allergies, foreign objects, and even cancer in some rarer cases in a young cat. Since there have only been episodes of vomiting total at this point, I wouldn't be particularly concerned as of yet. If you see this happening another couple of times over the next week, I think it is something worth investigating more. Hope this helps!

Cat throws up after eating in morning, but seems normal. Why?

It's possible Luna may just have some minor GI upset, or she is going too long in between meals if this has only happened twice and she is otherwise normal and happy. Other possibilities can include something such as a hairball that is leading to vomiting. Offering a bland meal after she vomits, or increasing the number of meals she gets per day may help with anything minor. If the vomiting continues, worsens, she shows other signs of illness, or you are just very concerned about it, it is always best to schedule a veterinary visit to rule out more serious issues. Internal parasites, GI illness, metabolic diseases, etc can all potentially cause vomiting as a symptom, so a complete exam is best to rule out any more serious problems.
