My cat vomited, now lethargic and not eating. Is it the new food?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 year old | 2 lbs

Cat was vomiting about 5 hours apart over 3 days. Stopped now but still lethargic and not eating. She can lie on her belly and purrs when picked up for cuddles I did try her on a new food was a tin food. Grain free brand.

It sounds as Lexy 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 urgently, 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.
