Oh no, it's so frustrating when a beloved pet starts peeing on the furniture! It's a common problem, but thankfully there are several steps you can take to figure out why it's happening and how to stop it.
First and foremost, the most important step is to take your cat to the vet for a check-up. Inappropriate urination is often the first sign of a medical issue, such as a urinary tract infection (UTI), bladder crystals, or feline idiopathic cystitis, which is bladder inflammation often linked to stress. A vet can run a urinalysis to rule out any underlying health problems that might be causing pain or an uncontrollable urge to pee.
Once you've ruled out a medical cause, the next step is a deep, thorough cleaning of the sofa. Cats have a powerful sense of smell, and if they can still detect even a faint trace of their urine, they will see that spot as an acceptable place to go again. You'll need to use a special enzymatic cleaner designed specifically for pet urine. These cleaners contain enzymes that break down the uric acid crystals, completely eliminating the odor rather than just masking it. Be sure to completely saturate the affected area, letting the cleaner soak deep into the cushions.
Next, take a look at the litter box situation. A good rule of thumb is to have one more litter box than you have cats. Make sure the boxes are in quiet, low-traffic areas where your cat feels safe. They should also be large, kept very clean, and perhaps uncovered, as some cats don't like lids. You could also try a litter attractant to make the box more appealing.
Finally, you can work on making the sofa a less attractive place to pee. You can cover the couch with a waterproof blanket or a plastic sheet for a while. Sometimes, simply changing the texture of the surface is enough of a deterrent. You can also try to change your cat's association with the sofa by playing with them and giving them treats there, turning it back into a happy place for lounging, not for peeing. It can take a bit of detective work, but by addressing potential medical, environmental, and behavioral issues, you can get to the bottom of it and save your sofa.
