Why is my cat pooping soft stool outside the litter box? Is she sick?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 8 lbs

Our cat keeps pooping outside her litter box and we've tried all the tricks already to have her stop. They are also always a soft/patty like consistency. We don't know if she's sick or what. We adopted her at age 1.

Poor Meechi! Normal cat stools are firm and dark in color, so it sounds like she probably has a medical problem of some kind causing her soft stools. It's very common for cats to poop outside the litter box when they have soft stools or diarrhea, so the underlying cause for this will need to be diagnosed and treated in order to get her to use her litter box appropriately. I would recommend taking Meechi to the vet for an exam as soon as you are able to. He/she can do some diagnostic testing, which might include a fecal exam for parasites as well as blood work to screen for a systemic illness of some kind, to help determine the problem and get her started on appropriate medication to treat it.
