I'm sorry to hear that Dylan is experiencing so much vomiting. If it is still continuing, he will need to see his veterinarian. Profuse vomiting can have several causes, but the most worrisome is a foreign body obstruction. This occurs when a cat eats something such as a hair band, a piece of string or a toy. It then becomes blocked in the intestine causing the cat to vomit. I hope this information helps!

My cat is throwing up yellow liquid. Do I need to see a vet?

It sounds as your cat 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/brown after eating cereal?

Hello, Vomiting can occur with dietary indiscretion but also intestinal obstructions, parasites, inflammation of pancreas, kidney or liver. If vomiting persists, I would advise you to follow up with Puma’s veterinarian to discuss abdominal x-rays, bloodwork and a fecal exam.

Why is my cat vomiting daily, eating grass, and what should I do?

Poor Sonic! If he's been vomiting every day for a month, a vet visit is definitely warranted as this is not normal. He may have a GI problem such as chronic pancreatitis or a foreign body in his stomach, a systemic illness like hyperthyroidism or chronic kidney disease, or may have an allergy or intolerance to something in his diet. Your veterinarian can do some diagnostic testing if needed to help determine what is causing the vomiting and get him started on appropriate 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.

My cat threw up yellow-green clumps but is fine. Should I worry?

If she only vomited one time and seems perfectly fine then I don't think there is a cause for concern. If the vomiting continues, she has a decreased appetite, or is lethargic then she should be examined by a vet for treatment.
