Litter Box Problems
Getting to the bottom of why your cat is eliminating outside of the box
It’s estimated that at least 10 percent of all cats develop elimination problems. These problems include not using the litter box, sometimes using the litter box, and using the litter box for either urinating or defecating, but not both. In all instances, this proves a problem for cat owners and it’s something you’ll want to tend to right away—once your cat has developed a particular non-litter-box surface or location preference for eliminating, it can be hard to address.
According to the ASPCA, the following common litter box problems might cause your cat to eliminate outside of her box:
- You haven’t cleaned your cat’s litter box often or thoroughly enough. Virtually all cats like clean litter boxes, so scoop and change your cat’s litter at least once a day. Rinse the litter box out completely with baking soda or unscented soap once a week.
- You haven’t provided enough litter boxes for your household. Be sure to have a litter box for each of your cats, as well as one extra. If your home is multi-story, you’ll need a litter box on each floor.
- Your cat’s litter box is too small for her or she can’t enter it easily.
- Your cat can’t easily get to her litter box at all times.
- Your cat’s litter box has a hood or liner that makes her uncomfortable.
- The litter in your cat’s box is too deep. Cats usually prefer one to two inches of litter.
- You’ve placed your cat’s food and water bowls beside her litter box. Generally, cats do not like to eliminate where they eat.
Multi-cat household conflict and medical problems can also cause litter box aversion. Even if you don’t actively see one of your cats blocking access to the litter box, this doesn’t mean conflict isn’t behind the reluctance to use the box. Similarly, if your cat had a medical problem that caused pain upon urination or defecation, this could create negative associations with the box even if the medical problem is now resolved.
Most cats prefer a quiet litter box location with sight lines—so they can see people and animals approaching—and multiple escape routes so the don’t feel cornered when using the litter box.
If you’re finding it difficult to consistently clean the litter box when you should, a great alternative is finding an automatic cleaner! Companies like LitterRobot provide comfortable, enclosed litter boxes that clean themselves, reducing litter smells and keeping your cat happy. LitterRobot even has a tracking feature so you can see how many times your cat uses the litter box, and source any health problems before they arise.*
Most cats prefer unscented, clumping litter OR they could be attached to the litter they used as a kitten—some cats adapt to litter changes no problem but some may feel wary of a litter they didn’t use when young. If you think your cat may dislike her litter type, try offering a few different types of litter in litter boxes placed side by side. Your cat will use the one she likes best.
Clean all accidents immediately and thoroughly with an enzymatic cleanser, available at most pet stores, designed to neutralize pet odours. Do not use an ammonia-based cleaner (urine is also ammonia), which can actually cause your cat to want to soil this area again.
If your cat has developed a non-litter-box location or surface preference for eliminating, you’ll need to make that surface or area less appealing. Try installing a bright light, or better yet, a motion-activated light, and covering the surface with tin foil, double-sided sticky tape, or the spiky underside of a carpet runner.
A Note on Urine Marking
Urine marking often gets lumped in with litter box problems but it is a whole different beast with different causes and solutions. Generally, a cat who is urine marking still uses the litter box but is also spraying other surfaces, usually vertical, with smaller amounts of urine. You may see your cat, tail held high and perhaps quivering, back up to a surface and spray it with urine.
