If the smell of cat urine greets you at the door upon entering, Tommy's not all to blame. A disliked setup of your cat's litter box and insufficient cleaning might trigger him to do his business elsewhere in the house. Correct these things so both parties can be happy.
Cleaning the Litter Box
The stench of cat urine in your house might come from your cat's dirty litter box. Scoop soiled litter and feces from his box at least twice a day -- once in the morning and once at night. Additionally, wash and sterilize the box once a week. Remove the litter, and rinse and scrub the box with hot water.
Properly cleaning Tommy's accidents is essential, because the scent of his urine might trigger him to revisit the soiled spot and pee on it again. Blot wet urine stains with paper towels. Press your foot on the towels to really absorb as much urine as you can. Then, soak the stain with an enzyme-based cleanser that eliminates odor-producing molecules, and allow the area to air-dry. To clean dried cat urine, use the same cleanser and scrub the area with a brush. Blot the stain with towels to absorb as much liquid and repeat the process if needed.
Medical Conditions and Marking
If Tommy is treating your house as his personal toilet, take him to a veterinarian to rule out medical conditions, such as diabetes, a bacterial bladder infection, kidney failure and incontinence. Tommy's house soiling might also be due to marking or spraying, which he does to communicate to other cats that they're entering his territory. Neutering Tommy and closing window blinds so he can't see outdoor cats might help remedy this behavior.
If Tommy refuses to use his litter box, determine what the problem is. He might dislike the location of the box or prefer a covered box to an open box -- or vice versa -- and unscented litter over scented litter. Place three litter boxes filled with different types of litter next to each other. The one he uses is the one he prefers. Use this same method to find out what type of litter box he prefers. Also, place the litter box in a ventilated, quiet area of the house so Tommy can do his business comfortably.
