Clean any places where your cat has peed inappropriately with an enzymatic cleaner. Your cat will stop marking in those places. Place treats close to where your cats pee inappropriately. If your cat is peeing on the bed, place treats there.
If your cat keeps peeing on the sofa, they may think they need to mark their territory. If you haven`t already spayed or neutered your cat, do so as soon as possible. Not only does that help control the pet population, but it also can eliminate your cat`s need to mark their territory.
“This behavior could be the result of a urinary tract infection, kidney disease, or diabetes. Other health problems that are painful, or simply make your cat feel “off” also could be to blame. For example, an older cat with severe arthritis might have trouble getting into a box with high sides or a cover,” says Lund.
Why does my cat pee on my stuff? According to the ASPCA, if your cat pees on your items, he is using his urine to mark the items. Cat marking is a behavior that originates with groups of cats trying to understand whose territory is whose. If cats leave the group, they claim their own territory.
Frustration, stress, or anxiety can sometimes cause a cat to change their urinating habits. Any change in their routine, such as a new person in the household or moving house, can lead to changes in urination. They may also “mark” spots in the house with their urine as a means of marking their territory.
Use an old towel to absorb as much of the cat pee as possible and throw it away when you`re done. Sprinkle baking soda over the affected area and let sit for about ten minutes. Pour some vinegar on the baking soda and let it fizz for a few seconds before blotting the liquid with a fresh rag.
Cat Urinating Outside of Their Litter Box – Health Concern

Firstly, and most importantly, it is essential to consider your cat`s health. Cats will often pee outside of their litter box (including on their owner`s bed) if they are suffering from a bladder infection or severe bladder inflammation.

Cats are territorial animals and they often use pooping and spraying outside the litter box as a way to mark their territory. New pets being introduced to the home may trigger your cat`s territorial instinct and lead to marking or pooping in places they shouldn`t be.
Eliminating outside the litter box is one way for your cat to mark their territory—and signals that they`re not feeling confident in their own home. According to Bell, cats might pee in unusual spots to mask an unfamiliar scent or pee on your favorite belongings because meshing your scent and theirs provides comfort.
But while it might be a biological problem, says Dr. Eatroff, cats usually pee on a bed due to an issue that is rooted in anxiety and stress, which can affect several hormonal and chemical balances in the body.
As a general rule, cats are sensitive when it comes to smells, but there are a few scents they hate that might just surprise you. They can`t stand citrus and as much as you might love the smell of fresh herbs, cats hate rosemary and thyme. Banana and mustard are a big no-no too, as well as lavender and eucalyptus.
Neutralize it!

Then you`re going to want to douse the spot with an enzymatic cleaner or simply make your own cleaning solution by combining (white or apple cider) vinegar and water in a 1:1 ratio. Because the vinegar is acidic, it will neutralize the bacteria in the cat pee, offsetting its odor.

Cleaning the area thoroughly with vinegar first and then applying an enzyme treatment will break down and evaporate the uric acid and your home will be free of cat odors. Vinegar and enzyme cleaners work on all surfaces: hardwood floors, carpets, mattresses.
Regular laundry detergent as well as other typical cleaning supplies, such as baking soda, vinegar, and hydrogen peroxide, can make the smell go away, but this is temporary. Some people recommend adding baking soda or vinegar to the wash.
Think food puzzles to engage minds and bodies, vertical space for climbing and surveying their domain, scratching posts, safe outdoor access (like a catio), window perches and interactive play. “Play is an important part of relieving stress,” Delgado says. “It helps cats release those feel-good hormones.”
Marking territory with urine is your cat`s way of dealing with stress. They feel anxious and are trying to relieve their anxiety by staking out their boundaries. Leaving their urine scent is the most emphatic way to say, “I`m stressed.” tract problems don`t clear up by themselves and require urgent attention.
Normal cat urine should be clear and pale yellow to amber in color. Any change in color — which you would notice if your cat urinates on the floor or in a sink — should be reported to your veterinarian.
But while it might be a biological problem, says Dr. Eatroff, cats usually pee on a bed due to an issue that is rooted in anxiety and stress, which can affect several hormonal and chemical balances in the body.
Cats are very sensitive animals, and small things that seem trivial might throw off their emotional balance. Peeing outside of the litter box is a common reaction in such cases. Stress triggers can also be changes in the living environment, for example, moving somewhere new with your cat. Cats are creatures of habit.
Cats pee on the couch for various reasons, including stress, anxiety, and medical problems. If your cat is urinating on the sofa, it`s essential to consult a vet to rule out any potential health issues.
Stress. Frustration, stress and anxiety are common causes of inappropriate urinating in cats and can be a way for cats to show they are not feeling too happy about something. You should try and work out what could be causing your cat to feel stressed so that you can remove or at least reduce, the stressor.
In particular, a cat that feels unsafe or vulnerable in any way can take to peeing on your bed. Similarly, a bored or under-stimulated cat can also start peeing in inappropriate areas as a way to communicate their need for more stimulation with you.

the most relevant questions and answers related to your specific issue

Q. I have a cat that defecates in the litter box but always urinates outside the box. It is very annoying.
ANSWER : A. Inappropriate elimination in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his eliminating outside the box.

If medical issues are ruled out, take a look at other reasons. Has there been a lot of unusual activity? Has you cat been left at home or boarded? Is the litterbox in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Is it big enough? Have you changed the type or brand of litter? Is there something attractive about the spot he uses? Cats dislike disturbances to their routine and may act out to express their dissatisfaction.

The general rule is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped daily, if not more often and changed completely weekly, washed with soap and water only. You can offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystals, it makes a hissing sound when wet that startles some cats and make them reluctant to use it again. The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure any other pets or people aren’t giving them a hard time around or in the litter box. It may take some investigation and experimentation to find your cat’s preference and accommodate him so that everyone is satisfied with the situation. And, when cleaning up pet accidents, don’t use any cleaner containing ammonia. This leaves behind a scent similar to urine.

Q. Our cat of six years has on two separate occasions has defecated on the living room rug and recently pee’d on the skirt of the Christmas tree.

Q. My cat seems to have lost control of her bowels and no longer uses her litter box even to urinate. She is 5 or 6 yrs and is in good health otherwise
ANSWER : A. If your cat has had a sudden change in litter box habits, it is always a good idea to rule out any underlying issues with a wellness check from your vet. Bringing in a urine and stool sample if possible can also help as tests can be run on these samples to check for common infections or parasites. If these are present, treating them usually helps resolve the problem of not using the box.

Loss of bowel control usually results in dribbling of feces or urine rather than complete accidents. If you are seeing this, it is possible that an injury to the hind end or problem with the nerves or muscles is happening and should be looked at by your vet.

If the accidents are complete (full amount of stool, big puddle of urine) your cat may be choosing not to use the litter box due to illness, a too-dirty litter, litter pans that are too tall (which may make older cats have a harder time getting in and out), or a litter substrate that was changed too suddenly. Sometimes, changing the environment your cat’s litter box is in by lowering the sides, moving food and water dishes away and returning back to a previously liked litter can help.

In any area of an accident, an enzymatic cleaner should be used. These break down urine and stool particles, making it so that your cat is less likely to be attracted to going there again. Moving stools to the litter box can also entice your cat to start going there again.

Q. My cat started to pee outside the litter box. What should I do?
ANSWER : A. Inappropriate bathroom use in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his defecating outside the box.

Once medical issues are ruled out, it’s time to take a look at other explanations. Has there been a lot of activity that wasn’t normal? Were you away and your cat was left at home or boarded? Is the litterbox located in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet, or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Have you changed the brand of litter or kind? Or is there something about the spot he has chosen to use that is attracting him in some way? Cats dislike disturbances to their routine and may act out as a way of expressing their dissatisfaction.

The general rule of thumb is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped at least daily, if not more often and changed completely on a weekly basis, and washed with soap and water.

You can also offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystal kind, since it makes a hissing sound when wet that can startle some cats and make them reluctant to use it again.

The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure other pets or people aren’t giving them a hard time around or in the litterbox. It may take some investigation and experimentation to find your cat’s preference and accommodate him so that everyone is satisfied with the situation.

Q. Cat is deficating on rugs, not litter box. Has never done this until this year. We drove from NY to FL, could there be a connection?
ANSWER : A. Sudden changes in bowel or litter box behavior can be caused by both behavioral or medical reasons. Scheduling a wellness exam with your local vet to rule out any problems (and also to bring in a stool sample) is the best first step. Problems such as digestive upset, constipation, diarrhea or even arthritis in older cats making it harder to get into the box can all cause this problem.

If your cat checks out healthy, it is possible that stress such as another person or pet in the home, age, or environment are causing the problem. Make sure that the litter used is the same, and if it needs to be changed that it is done gradually- cats are very picky about what they like as litter. Making sure bedding, food and water are not too close to the litter can also help as cats do not like to potty near these objects usually. For arthritic cats, a step or lowered box can make getting in and out easier to allow for proper use of the box. Keeping the box clean is also a must for cats.

As for cleaning up accidents, using a product such as an enzymatic cleaner may be helpful. These products break down urine and stool particles left in the accident area, and may deter your cat from using the spot as a bathroom again.

Q. My cat is pooping outside of the litter bix. He is 2 1/2. He did this as a kitten. It stopped then started about 3 months ago. Litterbox is clean.
ANSWER : A. Inappropriate elimination or house soiling can be a frustrating problem but with a bit of detective work on your part, there is hope. First, before deciding that this is a behavioral issue, any medical problems (diarrhea, constipation, fecal incontinence, pain on defecation, etc.) need to be ruled out and/or treated. If your cat receives a clean bill of health from your vet but is still eliminating outside the litterbox, then we need to consider that something about the box itself might be aversive to your cat. Cats can be quite finicky about their litterbox and toileting habits. Below I have listed common recommendations and cat preferences for litterbox use. Review the list and make any changes that could account for your cat’s aversion to defecating in the litterbox:
* Soft, fine-grained clumping litter (vs, coarse-grained, non-clumping litter)
* Unscented
* 1 – 1 1/2 inch depth (especially older cats or cats with hip problems)
* Larger pans (especially for large cats) – want to get whole body inside – poop just outside the box might mean the box is too small
* Open, non-hooded
* At least one shallow side to get in and out easily
* Easy to get to – not hidden away, preferably in areas they spend time in or near – and not near appliances that make scary, unpredictable noises (washers, dryers, refrigerators)
* Scoop minimum 1X/day – preferably 2
* Clean the litterbox with soap and water and put in fresh scoopable litter at least once/month (instead of just continuously adding)
* Some cats prefer to urinate in one box and defecate in a separate box, so you may need 2 boxes even if you just have 1 cat. Multi-cat households should have 1 box/cat plus 1 extra.

Q. We have a female cat that has started to pee in the floor. She has been fixed for years but refuses to use her box.
ANSWER : A. Sudden changes in litter box habits can be caused by a number of things. As with any sudden change in behavior, making sure your cat is healthy with a checkup from your vet is the first step. Common problems such as arthritis or even urinary tract infections may make a cat unable to use their box, or cause accidents to happen. Once the health issue has been addressed, you can also address the behavioral one. Cleaning with an enzymatic cleaner on accident spots will remove urine enzymes and deter cats from using the area again to go potty. For older cats with arthritis, using a box with lower sides or a ramp into it can help make getting in and out easier. If the litter has been changed recently to a different type, it may need to be switched back to the older litter and then gradually changed to the new as cats can be VERY picky about the litter type used. And lastly, making sure the box is clean and that food, water and bedding areas are not too close to the box can help encourage your cat to go appropriately.
