Why is my cat vomiting bile, not drinking, and very lethargic?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 1 year and 7 months old | 14 lbs

My cat started vomiting about 3 days ago. He was eating and drinking but began vomiting immediately after eating. I began giving him small amounts of can food. Yesterday he finally kept some down. Now he's not drinking. I withheld food for 24 hours, he just ate a little and it immediately came up with bile. He us about a year and a half old, up to date on all shots. He's constantly sleeping and no interest in playing. How can I help him?

It sounds as Biji 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 him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
