    Inappropriate Elimination in Cats: Why it happens and how to prevent it

    cat-urine-marking
    One of the most common complaints people have about cats is problems with eliminating (urinating or defecating) outside of the litter box. In one study, 57% of cats referred to a veterinary behaviorist were referred for this problem.1  In another study, roughly 1 in 4 cats surrendered to a shelter had a history of daily or weekly elimination outside the litter box.2 And a third study showed 9% of cats showing this behavior within three months of adoption.3
     
    While it is one of the most common issues cat owners face, it is also one of the most frustrating, and is one of the reasons there are countless numbers of cats now in animal shelters across the country. Many cat owners feel there is nothing they can do about the problem, but that isn’t the case. Making a few environmental changes can improve or even solve the problem and make everyone in the household much happier.

    1. Making a few environmental changes can improve or even solve the problem and make everyone in the household much happier.

    2. The best way to find a solution to the problem is to start testing different options by offering the cat a choice between the current option and something new.

    When a cat is urinating or defecating outside the litter box, there is usually one of three things going on:

    1. They are suffering from a medical condition that is affecting their use of the litter box when they need to go to the bathroom.

    2. They are spraying/marking their territory, which has nothing to do with them needing to go to the bathroom.

    3. They need to go to the bathroom, and they are choosing a place other than the litter box to go.

    The first step should be a visit to your veterinarian

    There are several medical conditions that would cause this kind of behavior, including urinary tract infections, bladder stones or crystals, kidney disease, diabetes, hyperthyroidism, and arthritis. Your veterinarian will conduct a physical exam and may evaluate a urine and/or stool sample, x-rays, and an ultrasound to rule out any gastrointestinal or urinary issues. If all urinary and other medical problems are ruled out, then it’s most likely behavioral.

    When the reason is behavioral

    The first type of behavioral issue is spraying or marking (these terms can be used interchangeably). It’s important to realize that spraying is all about social communication. The cat is leaving a message: “Fluffy was here at 10:22 a.m. on Monday.” The reason the cat would feel the need to leave a message could be due to stress or territorial issues. Both of these issues can be alleviated by environmental enrichment, prescription medications, or natural remedies, like pheromones and herbal supplements. Always check with your veterinarian for the proper use of medications and natural remedies. Some things that are safe for people or dogs are not safe for cats, so it’s important not to self-diagnose or take a recommendation from a pet store clerk or human pharmacist.

    The second type of behavioral issue that could lead to eliminating outside the litter box is toileting preferences or aversions. In the case of toileting preferences, the cat simply prefers to urinate somewhere other than the litter box. This could be because there is a recognizable smell in the area or he has come to enjoy the softness of the fabric in the area. In cases of toileting aversion, there is something about the litter box that is causing the cat to look elsewhere.

    Typical scenarios that would cause a toileting aversion:

    • The location of the litter box is undesirable. For example, if a cat is easily startled by loud noises, the litter box shouldn’t be in the laundry room or near a noisy appliance.Cat-on-stairs

    • It’s hard for the cat to gain access to the litter box. For example, an arthritic cat that is unable to easily jump up shouldn’t have a litter box that is up on a counter or down a long flight of stairs.

    • Use of the box is unpleasant due to litter odor, litter texture, or because the box isn’t cleaned regularly.

    • Something negative happened to the cat the last time he urinated in the litter box, so he won’t go near that spot any more. For example, the cat was right in the middle of urinating in the litter box when a housemate cat pounced on him, scaring him.

    What Can You Do?

    For all of these scenarios, the best way to find a solution is to start testing different options by offering the cat a choice between the current option and something new. For example, offer a second litter box with a different litter choice in the same area as the original box and see which of the boxes is used more regularly. If there isn’t a specific litter preference, you can also test for other preferences such as box type, box size, litter depth, or box location.
     
    Always make sure it’s easy, convenient and comfortable for the cat to access the litter box. And while you are testing, it may be helpful to block access to any area the cat has started preferring to urinate. For example, if they are choosing a certain closet or bedroom, close those doors. If they are choosing an area rug, roll it up and store it for a while.
     
    The sooner this issue is identified, the more likely it can be addressed and treated. It may be beneficial to consult with a veterinary behaviorist as soon as you’ve ruled out any medical issues. A behaviorist will create a concrete plan to follow that will solve the issue quickly with as little stress on the cat and the owner as possible.
