My cat's stomach is bloated and vets don't know why. What's next?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 11 months and 28 days old | 8 lbs

We have tried feeding her Nulo and Kiwi Kitchens (ie super low ingredient wet food) but she always has a super bloated stomach. It gets bigger/smaller randomly throughout the day. She has been dewormed and after multiple exams the vets have no idea what is causing this.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear about Pawny. There are other things besides worms that can cause a bloated stomach including liver or heart disease (something she would have been born with most likely), infection such as FIP (though she would likely be acting quite sick by this time), ileus or other gastrointestinal problem. I would say, if she is eating and passing stool normally, and it doesn't seem to bother her, I'm not too concerned. Other things you could try: A probiotic - I like Purina FortiFlora A prescription gastrointestinal diet from the vet x-rays to make sure there is no mechanical reason for buildup of gas Bloodwork to look for signs of infection or liver disease Other as recommended by your vet. Hope this helps and best of luck to you and Pawny!
