My cat on Methigel has an upset stomach and won't eat. What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 12.5 lbs

My 1yr DSH male cat is currently taking methigel for urinary ph, and in the last day or so he hasn’t been able to keep food down and seems to have an upset stomach. I’ve been forcing water in because it’s essential for his urine issues, but he doesn’t want to eat. He’s acting perfectly fine and cuddly. ~5 days ago the vet gave him an injection antibiotic (14 day) and anti inflammatory (again for urine issues while urinalysis is run) so I’m not worried about any infections.

Methigel may cause some stomach upset which could affect appetite. You can offer a bland diet or warm up Oliver's regular food to stimulate his appetite. A teaspoon of plain baby food can also be mixed in to get him eating again. If he doesn't begin eating again, have him rechecked by your veterinarian. A cat that does not eat for 2+ days is at risk of serious liver related complications.
