Why is my 8-month-old cat vomiting brown liquid? What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female

Hello! I have a cat that is about 8 months old. She’s been I vomiting a brown liquid for the past week or so. A month ago she’s been throwing up white foam and I was told it was vile from her not eating as often ( she plays non stop and will forget to eat unless I attract her towards her food). But now it has been a brown color. Her diet hasn’t changed she’s been on the same food since I’ve had her she has water at all times, so I can’t seem to find out what is causing her to throw up.

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting can be caused by many conditions primarily gastrointestinal in nature such gastroenteritis and gastrointestinal foreign body ingestion and obstruction or other conditions such as pancreatitis or kidney disease. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. Likely diagnostics to be performed include abdominal imaging and general bloodwork. Treatment would be based on findings. Good luck and have a great day!
