One of the most discouraging things about owning cats is the possibility that they will begin thinking outside the box, so to speak, and will take to peeing in corners, in boxes and even on your bed. The odour of cat urine has a disgusting scent that is, unfortunately, difficult to get rid of. What makes matters worse is that Miss Kitty can smell her scent better than you, so even though you've disinfected and deodorised, she will be attracted to the scene of the original crime. To stop a cat from wetting the bed takes perseverance and a few outside of the box techniques.
Soak your mattress and bedding with a solution made from three parts warm water and one part white vinegar. The solution will help neutralise the urine scent. "The ammonia smell (from the cat's urine) tells the cat that this is an elimination spot," noted Fanciers.com, a cat-lover's website.
Let the solution soak into the mattress and bedding for at least an hour, while protecting the floor under the mattress with newspaper or old towels.
Wash the mattress the best you can with a mild detergent and water, while protecting the floor under the mattress with newspapers or old towels. Washing will remove additional odours left behind after soaking the mattress in the vinegar-and-water solution. Allow to completely dry.
Wash the sheets and blankets on the pre-soak cycle in your washing machine. Soaking will help eliminate additional odours.
Soak the mattress with a commercial deodoriser like Anti-Icky-Poo, to cover up any remaining scent of urine. Allow to completely dry.
Hang the sheets and towels outside and soak with a commercial deodoriser. Allow to dry completely.
Make your bed, putting a waterproof mattress cover on before the sheets and blankets. The waterproof covering helps hold in additional odours and protects your mattress if your kitty decides to revisit the scene of the crime.
Spray the bed with a commercial pet repellent to help dissuade kitty from using your bed as a litter box.
Place jingle bells all over your bed after making it in the morning. When kitty jumps up, the bells will startle her causing an abrupt about-face. If all else fails, buy a remnant of non-slip carpet that has pointy grippers on the underside, and toss it on your bed bottom-side up. Cats don't like the feeling of something jagged under their feet, noted pet-care website 123-Pet.com.
Scoop or change your kitty litter often, recommends 123-Pet.com. Cats don't like using a dirty litter box and will find other places---especially soft places---to go. In multi-cat households, try to give each feline her own litter box. Cats will share each others' boxes, but the additional choices might help alleviate accidents. If you ever see your cat on the bed looking suspicious, spray her with water from a cheap spray bottle, advises Fanciers.com. Take your kitty to the vet to be sure no physical reason causes the mishap. Often cats will pee in soft places if they have a urinary infection. "Spraying is more often a behaviour problem and urination is more often a medical problem," noted Fanciers.com. Do not use ammonia or ammonia-based cleaners. The ammonia scent smells like urine to your cat, which will attract her back to the spot.
