Instructions
Bring the cat to a vet for a medical examination. It could start urinating on the sofa because of health conditions such as urinary tract infections, kidney diseases, liver diseases, hyperthyroidism or ladder stones. You should rule out these causes before doing anything else.
Clean the sofa with special pet urine cleaner, as cats often continue to urinate in places where they can smell their urine.
Clean the litter box if the cat turns out to be healthy, as cats often refuse to use a dirty litter box. You should clean the litter box at least daily and wash the box weekly using a mild, ammonia-free cleanser.
Try a different type of litter or a different location for the litter box. You can place several litter boxes filled with different types of litter around the house to find out your cat's preferences. Pets.Ca recommends a sandy, unscented litter and an open litter box.
Place the cat's food and water bowls near the sofa, because cats don't like to urinate near their feeding areas.
Make the sofa unattractive to the cat by covering it with thick plastic, aluminum foil, double-sided tape or pet repellents. You can also place special mats on the sofa that emit a mild static pulse when the cat touches it.
Startle the cat if you see it trying to urinate on the sofa. You can shake a can full of coins, blow a whistle or squirt a little water on the cat with a water gun.
Reward the cat if it uses the litter box using praises and treats.
Confine the cat in a room if all other attempts fail. Place its litter box, food and water bowls, toys, scratching post and bed inside. When it starts using the litter box again, gradually allow it to access larger areas of the house.
How to Stop Cat Urination on a Sofa
According to Pets.Ca, inappropriate urination is the most common reason for cat owners to give up their pets. It makes up 30 to 60 percent of all feline behavioral problems that vets encounter. Besides damaging the sofa, inappropriate urination can also harm the bond between the owner and the cat. Several factors can cause a cat to urinate on the sofa, and they can be medical or behavioral. Cat owners should be patient in trying to solve inappropriate urination, as it might take several attempts for the problem to go away.
