Difficulty: Moderately Easy
Step1
Consider setting up extra litter boxes. Many cats like to have one litter box for urine and another for bowel movements. Buy one additional litter box for every cat you own.
Step2
Take your cat to the vet. If your cat suddenly stopped using the litter box, it may be sick.
Step3
Think about getting your pet neutered or spayed. Male cats and female cats in heat often stop using the litter box. They're trying to let other cats know they're available.
Step4
Clean up any messes with an enzyme cleaner. Cats will often return to the same spot they already visited. If you don't fully get rid of the smell, chances are your cat will continue do its business in that spot. If your cat is still using that area, block it off and put aluminum foil or double-sided tape over the spot.
Step5
Make sure you keep the litter box clean. Cats are clean animals and some won't use a dirty litter box. Scoop out any solid material, replace the litter and rinse it out once a week.
Step6
Decide where to place the litter box. Most cats prefer it to be in a quiet place.
