Cat Pooping Outside the Litter Box? Here Are 5 Possible Reasons Why

86 comments

Has your cat suddenly started defacating or urinating outside the litter box? It can be frustrating and downright gross to have to repeatedly pick up your cat's, uh, "treasure" off the carpet. Most cat owners have experienced this issue at least once or twice.

For the occasional "outside the box" pooper, it might be a one-off. But if your cat is choosing to go outside his litter box on a daily basis, he's trying to tell you something is up.

It's important to remember that your cat isn't doing this to spite you; cats aren't vengeful creatures. Mr. Whiskers is trying to communicate with you in one of the only ways he can. Here are five possible reasons your cat might be avoiding the litter box.

1. Rule out medical reasons.

Observe your cat when he "goes" and look for signs of straining or discomfort. Your cat might associate digging in the litter box with uncomfortable elimination, so they may begin avoiding going inside the litter box.

If your cat is straining,  or cries out while trying to go to the bathroom, it signals that illness (not behavior) is the reason behind your cat's pooping misadventures; a vet checkup is likely necessary. 

2.  Keep it clean!

Cats are fastidiously clean creatures with extremely sensitive noses. Their sense of smell is approximately 40 times as powerful than us humans! Imagine if you had a roommate and you came home to a stinky bathroom - you wouldn't want to use it, would you?

If you find your cat avoiding the litter box unless it's fresh and clean, try scooping daily to give your cat a nice, appealing place to go. If you have a multi-cat household, you might want to consider a litter scoop that comes with bags attached to make scooping and waste disposal quicker and easier.

3. Try different litters.

Due to their sensitive snoots, some cats may prefer unscented litters. A perfumed litter might be too strong for a cat's sense of smell. If you are using perfumed litter, your cat might not like the strong scent. Try switching to a non-perfumed litter.

If you're using a granulated litter, try a finer grain clumping litter. Cats may tend to like the feel of finer litters - whether this is because a cat instinctively likes to cover their feces in dirt or sand, or just a weird personal cat preference, cats generally spend over 20 seconds pawing around in the litter. So it's important for your cat to actually want to use the litter you choose. 

The depth of the litter also might not be enough for your cat to adequately cover their business. So if you notice some bare patches from where your cat has tried to bury their feces, try increasing the amount of litter you pour.
 

4. Consider location, location, location.

Even though cats have been domesticated, they can still have strong wild instincts. When your cat uses the litter box, they know they are vulnerable to attack. You want to situate the litter box in a quiet, private location where they won't be disturbed by loud, sudden noises that would scare them away from using the litter box.

If there are other cats in your home, the litter box may be a source of contention. Your other cats may be intimidating your cat during litter box visits, causing them to avoid it and eliminate outside the litter box.

Make sure the box is in a location that offers a clear and easy escape route for your cat and, even better, make sure you have several boxes in different locations so your cat has options. 

5. The box is too small.

Your cat might be like Goldilocks: their litter box needs to be just right - not too big, not too small. Your cat's litter box should be at least 1.5x their length for them to comfortably maneuver. A cramped litter box doesn't give your cat the ability to turn around and dig, making their usual bathroom routine uncomfortable.

If you have an older cat who suffers from arthritis, a high-sided box may be making it difficult to get in and out of the box.

    My male, neutered cat is between 10 and 15. He is the only pet in the home. He goes through periods when he defecates outside his litter box — sometimes within a foot. I live in a two-bedroom apartment, and have three litter boxes. I scoop them at least every other day, usually daily. I’ve switched to a fine, unscented litter. I’ve tried open boxes, as well as the top-entry type. When I clean up the messes, I use a spot cleaning machine with a pet stain and odor solution, and I spray the spot with Nature’s Miracle once it’s clean. What am I missing?

    My cat has been great at using the litter box but now we got baby kittens and he is now randomly pooping on the couch. Could the kittens be a reason? They are in the basement and he is up stairs. This has only happened twice but I don’t want it to be a thing. What should I do

    Hi Roxanne. I know you said you tried every kind of litter, but I wanted to suggest a couple more jsut in case. I’m currently using Yesterday’s News. It’s made of recycled newspaper so maybe it will be more familiar if they poop on newspaper now. I also found a new one called Pretty Litter. It’s made of descant beads so it’s highly absorbent and great at odor control. It looks and feels like sand. When I tried that one though, I had to get a new box so that it would keep such light particles from flinging everywhere. Which maybe it could be a box issue and not a litter issue for your cat. I got A top entry box, which literally looks like a plastic tub with a hole on the top. So maybe the cat can feel more secure jumping into a completely enclosed, dark space. Good luck!

    In response to Lee and Roxanne’s posts, you might want to try soil in the litter box instead of litter or mixed with litter to mimic the outdoors. We had a kitten that wouldn’t use the litter box and I went outside and got some soil from the flower bed and sprinkled it in the box and set the kitten in it and she used it and we never had another problem after that. Good luck.

    Roxanne – I once had a kitten that would not go in the litter box. I was finally successful when I caught him mid-pee….picked him up while still peeing…and he finished peeing in the litter box. He then found out he could cover his pee and ever since he never went outside of the litter box.
