My cat has diarrhea, hides, and won't clean herself after new food.

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 5 years and 5 months old | 10 lbs

Changed diet in Sophie, from wiskas to nutro feed (both dry) about 2 weeks ago. She’s been hiding, usually hides when she’s stressed or there’s a big change, she also has diarrhea and doesn’t seem to be cleaning herself in that area, doesn’t like to be touched near her bum (tried to clean it for her and she freaked out)

Poor Sophie! If a diet is going to cause diarrhea, it usually happens within a few days of the diet change. Also, diets need to be slowly transitioned over the coarse of 7 days. If this is the case, I recommend to switch her to a different diet or even back to her old diet because you know she does well in that. If that’s not the case, pets can get diarrhea for many reasons and bacterial over growth and parasites are the most common. If Sophie is feeling bad enough that she is not cleaning herself, she needs to see the veterinarian. Cats are naturally clean animals so when they allow themselves to have stool on them, they are usually feeling pretty bad. Try to bring in a stool sample for testing. I hope this is helpful and please feel free to post any additional questions.
