Why is my cat pooping outside the litter box with another cat?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 4 years and 2 months old | 11.5 lbs

I have two cats that are 3 years old and females. Recently the bombay cat started pooping outside of her covered litter box. I have two covered liiter boxes in the house. I suspect that my other cat, Missy who is a tabby and 3 years old is stopping Pooky from using the litter box as she is very territorial and jealous of Pooky. Tonite I have separated them so I can see if Pooky wil use her litter pan. If you have any other suggestions, I sure would appreciate it if you would advise me. Thanks,

Hi. I would recommend a few things. Uncover the boxes. Add a third box. And isolate them from each other for a bit. Then introduce, after showing them where the boxes are. Also recommend full exam and labs to rule out any medical potential causes for inappropriate defecation. Good luck.
