Dealing with Feline Inappropriate Elimination

Cat Pee

Inappropriate urination can take many forms and have several causes. Sometimes a cat seems to suddenly forget her litterbox training,

urinating everywhere except where she’s supposed to

. Your cat may start to urinate in hidden areas of the house or choose to urinate on furniture, rugs or clothing.

Sometimes, a specific spot is used over and over again. At other times, new places are chosen, from hidden areas to the middle of the room. You may find one large pool of urine or many tiny spots all over the house. Inappropriate elimination is the most common behavior problem in cats, according to

Causes of Inappropriate Urination

There are several reasons a cat will abruptly stop using her litterbox. Many issues are medical in nature and require veterinary attention. Others are solely of a behavioral nature and require a different approach.

Before attempting to treat a cat for a possible behavior issue, it’s important to make sure there isn’t a medical issue that must first be addressed. Your veterinarian can perform blood tests and a urinalysis on your cat to find out if there are any medical conditions that may be causing the unwanted behavior.

Sanitation Issues

Cats are clean creatures by nature. They also have a much more developed sense of smell than people do. If you can smell a faint urine odor, imagine what it smells like to a cat. It’s possible to prevent inappropriate urination simply by maintaining a clean litterbox.


Some cats are easily stressed, which can cause a change in behavior. A change in the household, such as a new pet, baby or any other change in the family dynamic, can cause your cat to urinate in inappropriate places.


4 Tips for Bringing a New Pet Home

This is not for spite, as many cat owners suspect. One of the ways a stressed cat reacts to change is to stop going into areas perceived as dangerous. If a cat is unwilling to go into the area where her litterbox is, she’ll find another place to urinate. Rubbing her nose in it is not a good way to teach your cat this place is not where she should urinate. As with dogs, trying to correct a behavior well after it has taken place will only serve to confuse the cat and, worse, may exacerbate the problem.

Marking Territory

Spraying is probably the most well-known form of inappropriate urination. When cats spray, they hold their tails straight up, back up to the furniture or wall, and quiver their tails while distributing a relatively small amount of urine for the purpose of scent marking her territory.

The intact male is the most common perpetrator of this act. A neutered male will spray and, rarely, even a female will give it a try. Any cat who believes her territory is being invaded by an unwelcome visitor will engage in this activity.

Factors outside of the house can also trigger a cat to spray. Cats seen through a window can be perceived by your cat as a threat to her territory. It may take some detective work on your part in order to find the cause. Discontinuing access to the view is one way to remove the perceived threat and solve the problem.

It’s also possible to avoid this cause of inappropriate urination by having a male cat neutered before he becomes sexually mature, which occurs at about six months of age.

How to Stop a Cat From Inappropriate Urination

Start by thoroughly cleaning soiled areas around the home to remove all traces of urine. There are several products on the market to help you locate the source of urine and eliminate the smell from almost any surface. The most effective products use enzymes to eliminate the urine and odor.

Using strong smelling deodorizers is no substitute for removing odors. Due to a cat’s sensitive sense of smell, these deodorizers may be considered offensive. In any case, the urine odor will still be apparent to the cat and, most likely, to you as well. In the event of spraying, a feline pheromone spray can be applied to the area after it is cleaned to trick the cat into believing that the scent mark is still present without the offending odor.

Buy the Right Litterbox

The size and configuration of a litterbox can be an important factor too. When choosing a litterbox, consider the size of your cat. The box should be large enough for her to comfortably walk into and turn around inside. Small kittens may find the sides of the litterbox too tall to easily climb over, making a box with shorter sides necessary until the kitten grows enough to use a larger box.

Talking about size, many items sold as litterboxes are, in fact, too small for the average-sized adult cat. In addition, while a covered litterbox may sound like a good idea, a cat may not feel comfortable squeezing herself into this cramped space. If you’re unable to find a litterbox that is large enough at the local pet store, think outside the litter box.

Peruse the storage container section of the local discount store or home improvement center. Look for a large sturdy box that can be easily cleaned. Those made for under-the-bed storage or any other large low-sided box work well.

Provide Multiple Options

If there are multiple cats in the same household, the rule of thumb is one litterbox for each cat plus one extra litterbox. So two cats should have access to three litterboxes situated in various areas of the house. Each cat may or may not choose to use the same litterbox over and over again, but has the option of urinating elsewhere if another cat is blocking access to one of the boxes.

The location of each litterbox is also important. Place boxes away from high-traffic areas. Cats require privacy just like we do. If your home has more than one level, it’s best to have at least one litterbox on each level.

Remember to reward your cat for using the litterbox. Reinforce good behavior with calm praise, gentle pet or favorite treat.

Choose Your Cat’s Favorite Litter

Consider what goes into the litterbox. Cats may prefer one type of litter over another so strongly that they refuse to use anything except their favorite. If a brand or type of litter is changed, this can be enough to cause the issue.

Litter choices are endless. In addition to non-clumping and clumping clay litters, both of which are widely available, there are litters made from recycled newspapers, pine, corn and wheat as well as crystals (made from silica). Some contain baking soda or carbon to absorb offending odors while others are scented—the latter may be offensive to cats.

There are also brands that contain an attractant to encourage cats to use their litterbox. Sometimes this option will do the trick when all others have failed. Once you find a litter that appeals to your cat, it’s best to use it continuously.

Maintain Litterbox

Scoop solids daily, thoroughly clean the box and replace with new litter at least weekly. Harsh chemicals should never be used on a cat litterbox for the purpose of routine cleaning. Mild soap and water is best, but if a more powerful disinfection is desired, diluted bleach can be used. A freshly made solution of one part bleach to 30 parts water works well for most disinfecting purposes. Remember to rinse completely and dry thoroughly before refilling the box.

Reduce Stress

Cats are quite sensitive to their surroundings. Like people, they react to noise, activity and changes in their environment, and have the same need to feel safe and secure. Cleaning, feeding and play times should occur at the same time each day. Cats are comforted by predictable routines.

Using a feline pheromone spray or diffuser could help avoid behavior issues before they start. Start usage of either product a few days to a week before a possibly stressful situation, such as a move, new pet, impending guests or departure. Never use the spray on the cat and also be careful not to use the spray while the cat is in the room. These artificial pheromones mimic those released from the cat’s cheeks and paw pads that are used to scent mark territory.

Inappropriate Urination Has Put an End to Many a Cat’s Life

This isn’t because it’s a deadly condition in and of itself, but because many cat owners are unable or unwilling, or simply lack the knowledge to treat the causes of this behavior. Many cats with inappropriate urinating behaviors are either euthanized at the owner’s request or brought to shelters to ultimately face the same unfortunate fate.

If you’re facing this dilemma, please use the following tips and speak with a veterinary professional for help to avoid having to resort to these drastic measures. Once any possible medical issues are ruled out, it’s time to consider behavior issues as a cause.

Try to see the world from your cat’s point of view. Many behavior issues can be resolved by understanding the reasons for this behavior and addressing them accordingly.

Solving the issue of inappropriate urination could require some dedication on your part. Inappropriate urination issues with your cat can be solved through a team effort between you, your veterinary office and these helpful tips.
