Kitty may diligently urinate in the box but what do you do if she decides she’d rather leave her solid deposits somewhere else? It can be very confusing for a cat parent when the cat faithfully uses the box for one function but refuses to use it for the other.
Rule Out Medical Issues
Even if you’re absolutely certain that the problem is behavioral, you need to have your cat examined by the veterinarian to make sure there isn’t an underlying medical problem. There are a number of medical issues that could be causing kitty to feel uncomfortable about pooping in the box. If she experiences constipation, for example, she may associate the box with her discomfort and attempt to go somewhere else. If your cat is older and has arthritis, it may be difficult for her to perch on the litter substrate in order to eliminate solids. If you have a covered litter box, she may feel cramped in there while perching in position to poop.
There are a number of intestinal problems (inflammatory bowel disease for example) that commonly result in cats defecating outside of the box. The cat may experience cramping and the discomfort causes her to try to eliminate wherever she is at the time. She may also become so uncomfortable that she can’t make it to the box.
When you take your cat to the veterinarian, try to bring along a sample of her stool so the veterinarian can run some tests and also examine the appearance (for signs of blood, mucous, hair, etc).
Don’t overlook this very important first step if your cat is pooping outside of the box. I have lived with a cat who had inflammatory bowel disease and know how much pain he must’ve felt when his intestines starting cramping. I also have a number of clients who have cats with intestinal problems. Getting your cat diagnosed and on appropriate medication (and in some cases, prescription formula food) as soon as possible will be most important.
There are some cats who don’t like to defecate in the same area used for urination. For some cats it may be that urination has more territorial connection or it may just be a quirky feline instinct. Regardless, a simple solution you can offer is to make another box available for defecation. Don’t place the box right next to the original box or it’ll just be regarded as one big box and kitty will still not poop in it. In many cases you can put the second box in the same room (depending on the size of the room), but in other cases, you’ll have to locate the second box elsewhere. Your cat will certainly let you know when the location pleases her.
It typically takes a cat a bit longer to defecate than urinate. In a multicat household where there is even the smallest amount of tension, it may be too stressful for a cat to hang out in the litter box long enough to poop. If the box is covered, wedged in a corner or hidden in a closet, this truly reduces the cat’s escape potential. She may feel it’s safer to poop in another location that allows her to have a better view in case an opponent is coming. The location she chooses may also give her a better opportunity to get out of there more safely.
The solution in this case may be to provide uncovered boxes and to make sure there are enough boxes located through the house.
Some cats, for whatever reason only they seem to know, have a substrate preference when it comes to the feel of the litter for defecation versus urination. Perhaps it has something to do with the amount of time they spend in that perching position for pooping. If you think that might be the case, offer another litter box with a litter that has a different texture. In general, cats prefer a soft, sandy texture when it comes to the litter substrate.
Last But Not Least: Cleanliness
A cat may decide that the box is too dirty if there is any waste already in there. She may urinate but then feel it’s now not clean enough for her to defecate in. Understandably, you can’t stand over the box 24 hours a day with a litter scoop in your hand in order to remove waste the nanosecond it touches the litter. Just make sure you’re scooping at least twice a day and have more than one litter box so there will be a greater chance that kitty will find a clean patch of litter for defecation.
Want More Information?
Your veterinarian should be your first stop whenever there is any kind of litter box problem. Have your cat examined and if she gets a clean bill of health, talk with your veterinarian about your specific litter box set-up. If you’d like more specific information on litter box issues, refer to any of Pam’s books including Think Like a Cat.
