Q. My cat started urinating outside the litterbox. What can I do?

Elaine Wexler-Mitchell names potential factors as to why your cat is urinating outside the litterboxElaine Wexler-Mitchell, DVM, says: Urinating outside the litterbox and spraying are two different problems. Cats urinate outside the litterbox onto horizontal surfaces, such as the floor, not onto vertical surfaces as in spraying. Inappropriate elimination is either caused by urinary tract disease or behavioral problems. Behavioral problems that may cause inappropriate elimination are difficult to determine because situations that create stress or anxiety for your cat may not be apparent to you.

Make sure that you are keeping your cat's litterbox as clean as possible by scooping it twice daily. If you changed the type of litter you use in the litterbox, your cat may not like it; cats have preferences for certain types of litter. If there are no obvious litterbox factors, have your cat examined and her urine analyzed. If urinalysis and examination uncover a medical problem, your veterinarian will make treatment recommendations.

If there are no obvious medical problems, you need to work with your veterinarian or a behaviorist to identify the factors triggering the inappropriate elimination behavior. As with other behavior problems, the best chance for stopping inappropriate elimination is with early intervention. It is unrealistic to think that a behavior pattern that has been in existence for more than a couple of weeks can be turned around within a few days, so be patient and compliant with your vet's recommendation. You will achieve the best results with a combination of behavior modification and antianxiety drug therapy. Give your cat plenty of attention and set aside at least five minutes twice a day to play with your cat to decrease stress and boredom and create a new behavior pattern.

You will need to remove urine stains and odors so that your cat is not attracted back to the same spot. Avoid cleaners with ammonia as they intensify the smell of urine and make your cat want to eliminate in the same area. In addition to cleaners, you can create an obstruction or spray a repellant on the affected area. To create an obstruction, simply close the door to the affected room, place an additional litterbox on the area, put a plastic carpet runner placed upside down on the area, lay down aluminum foil, or play with and feed your cat at the site. Repel your cat from affected areas using solid air fresheners with a fruity or flowery scent. Cats do not like fruity or flowery scents; they only like their own. There are numerous brands available in grocery and drug stores.

If these steps are not successful, you can also use herbal calming remedies and antianxiety medications along with behavior modification to treat inappropriate elimination caused by behavioral problems. Some of the prescription drugs used are amitriptyline (Elavil), clomipramine (Clomicalm), buspirone (BusPar), paroxetine (Paxil), and fluoxetine hydrochloride (Prozac). Some cats can be weaned off the medication eventually, but others need long-term treatment to keep their behavior under control. You should avoid hormone therapy for inappropriate elimination due to the potential for side effects, such as diabetes mellitus or mammary cancer. Curing an inappropriate elimination problem requires early recognition, owner commitment, and patience.

I beg u please do not put your cat down. If this is a new behavior hopefully it can be corrected. I have watched alot of cat shows with that guy with all the tattoos. Try to reach him if you can or a a behaviorist in your area. Here is my 2 cents your cat is bored, do you play with him like vigarous play with something on a stick. Did u try a new kind of litter box remember the other one could still smell like sickness to him. Does he have a catch perch to climb all cats like to be above ground, grooming and my time with kitty do u give him your time. They like to feel needed. Take food and water away and only put down 3 times, morning for breakfast, afternoon or if u work a small amount, again at dinner time do not leave either food down at night. Nothing in nothing out. I truly hope this helps with your kitty but a behaviorist (Jackson Galaxy) is his name and he is amazing your poor little guy isnt happy either

My 2 1/2 year old cat has been choosing to pee right outside the litter box. It's never even a foot away from the litter box. And I'm confused because sometimes she goes in, and other times not. I'm worried about her health, but also can't afford too many tests to be ran if it's not something serious. Are there any other reasons a cat might choose to sometimes do this?
