How to stop my cat from peeing outside litter box after new cat?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 2 years and 9 months old

Hi my cat is a little over 3 years old we chose to bring in another cat into the house and that did not work out to do cat's Behavior. Since we had gotten rid of the other cat original three year old cat has started peeing in the house outside of his litter box. Is there anything else I can do to stop him.

You could try a Feliway diffuser or spray and see if that helps. If it continues then have him checked by your vet to make sure he doesn't have a medical issue, like a urinary tract infection. You could also talk to your vet about trying an anti-anxiety medication, like Prozac or Trazodone to see if that helps.
