Cat odor usually comes from urine, litter box buildup, saliva on fabrics, or dander trapped in soft surfaces. The fix is to remove the source, not just cover the smell.
Key takeaways
- Clean the source first, then deodorize the room.
- Use an enzyme cleaner for urine and sprayed areas.
- Scoop the litter box daily and wash it weekly.
- Increase ventilation and wash soft fabrics regularly.
- Check with a vet if the smell changes suddenly or your cat starts avoiding the litter box.
Where the smell usually starts
Most home cat odors come from one of four places: litter boxes, urine outside the box, bedding and blankets, or fabric surfaces such as couches and rugs. Multi-cat homes can also smell stronger when one cat is stressed or trying to mark territory. See how to tell if cats are getting along if you suspect tension is part of the problem.
How to clean it
- Blot fresh urine immediately with paper towels. Do not rub it in.
- Use an enzyme cleaner on the affected area and let it fully dry.
- Wash washable fabrics in the hottest safe water with unscented detergent.
- Vacuum carpets and upholstery after they dry, ideally with a HEPA vacuum.
- Open windows or run air circulation to clear lingering odor.
How to prevent it from coming back
Scoop litter boxes at least once a day, fully dump and wash the box on a regular schedule, and provide enough boxes for the number of cats in the home. Brushing your cat and washing bedding also cuts down on dander and loose fur. If your cat is suddenly soiling outside the litter box, talk to a veterinarian.
