My cat has diarrhea and poops outside the litter box. What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 6 lbs

my cat poops diarrhea and poops outside the litter box. She used to have normal poop and the habit of going in the litter box. But a couple years ago she started going outside the litter box and we noticed she had diarrhea. She is an outdoor cat and she'll eat rodents and also anything she can find in the kitchen which may be part of why she has diarrhea. We're moving and my mom wants to get rid of her so she doesn't poop in the new house. Please give any advice/help you can so I can keep her

There could be several causes for Yokie having diarrhea. She would benefit from an exam with a veterinarian - take a fresh stool sample with you to the appointment for evaluation (litter on it is ok!). Some of the more common reasons for diarrhea in cats include intestinal parasites (which she could have gotten from eating outside critters), Irritable Bowel Syndrome, and intestinal lymphoma. Your veterinarian will be able to prescribe special dewormers based on her symptoms and may recommend a special food or other medications to try out and see if that helps with the diarrhea. You can also try "ProPectalin AntiDiarrheal Gel for Dogs Cats", but it should not be administered long-term.
