Why is my cat lethargic with yellow liquid poop after eating salmon?

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 7 years and 1 month old | 20 lbs

My cat is pooping out yellow liquids poo. He's very lathargic and issolating himself. He is a rescue and we discovered the food he was on he didn't eat for the first 3 days we had him so we gave him wet food and he ate it right up. After a couple weeks he was fine until he ate some salmon and now he's having this weird poop. What could be going on?

Stress can certainly affect cats and may cause diarrhea or not eating. But if Will is continuing to hide and not eat he needs to be seen by a veterinarian. He may have a parasite infection or other infection that the stress of a new home has caused to surface.
