Why is my litter trained cat suddenly peeing outside the litter box?

Updated On September 23rd, 2025

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

My cat who we adopted at Christmas has been litter trained and was doing fine for 3 weeks. Then yesterday she randomly ly starts peeing everywhere! In all the corners and won't stop. No big changes in the house, she's 2-3 years old. What gives?

When a cat who is litter box trained suddenly starts urinating in the house, that can be a sign of a medical illness such as feline idiopathic cystitis or bladder stones. I'd take Dixie into the vet today or tomorrow to get this checked out. I hope this helps!
