Urinating Outside the Litter Box in Cats: Causes & Treatment
By: Dr. Clayton Greenway, B.Sc., DVM | Aug 3, 2019
Whenever our pets are eliminating inappropriately, whether it be urination or defecation, it is caused by two things: medical reasons or behavioral reasons. So the first thing we have to do is rule out any medical problems.
I recommend you see your veterinarian and perform blood work and urine testing to make sure there is no medical issue that is causing the urinating outside the litter box. Inappropriate urination can be caused by a urinary tract infection, diabetes, renal disease, hyperthyroidism, neurological disease or other ailments that can be found by running diagnostics. If a medical condition is found, then the appropriate treatment can be implemented and the condition may resolve.
If no medical condition is found, then we have to consider behavioral reasons as a source. Cats are very in tune with their environment and so there are so many stimuli that can cause them to become anxious or change their behavior. For example, I remember a patient that stopped going to the litter box because an owner started storing luggage near the litter box. Cats can also perceive things that we can’t, so a high-pitched sound that doesn’t bother us, may bother them and cause them fear around the litter box. Now you may go hunting for these things, but in the end, it’s rare to find. It doesn’t take much for a cat to start eliminating inappropriately and once they do, the reason they started doing it may be gone but they are now just continuing the behavior. The longer you let this go on, the more it’s going to be ingrained and difficult to resolve. There are some strategies you can employ to focus their attention on the litter box.
Place Treats Near the Litter Box
You can start putting treats near the litter box but I always tell people not to let the cat know you’re putting them there. This way they just happen to find them. They may start visiting the litter box just to see if they’ve shown up again and since they’re there, they might as well use the litter box.
Place Litter Boxes in Various Areas of the House
Keep in mind that cats can develop issues like arthritis which can make it difficult for them to go up and down the stairs and this may be the cause of why they’re not visiting the litter box.
Make Sure Your Cat Fits in Their Litterbox
When a cat is really overweight and large, they may no longer fit in the litter box and it may not be comfortable to use it. I often have owners buy a large bin, cut the sides really low, put it in a garbage bag and sprinkle litter on top of it creating their own litter box with a much larger surface area and low sides to it so it’s very easy to step in and out.
Products to Attract Your Cat
There are also products that you can sprinkle in the litter that is supposed to attract them to it. These can work in some cases but not in others.
Provide Environmental Enrichment
Restrict Access to Certain Areas
If they are eliminating in a particular spot, like on a bed or in a bedroom, you can restrict access to this area. Always clean the area where they have been eliminating very thoroughly. Even a small amount of debris or odor will make them return to that place and think it’s an appropriate place to eliminate.
Lastly, a lot of cases do take medication to solve these issues. I would have to say that anxiety, in general, is usually the cause of the problem. Whenever I say this to clients, I always get the same response. They say: you clearly don’t understand my cat, he or she is not stressed. But what clients don’t understand is that although you’re providing a very nice home for your pet, we have to remember that these were animals that lived in the outside environment and engaged their world by hunting and hiding. Many cats can develop stress just by being an indoor cat. You can speak to your veterinarian about anti-anxiety supplements and anti-anxiety medication to use as a trial if the aforementioned strategies do not work.
