Key Takeaways
- Not covering poop is a natural behavior for some cats and can stem from their desire to declare territory, especially in multi-cat households or areas where they sense other animals outside.
- Issues with the litter box, such as size or cleanliness, can deter cats from burying their feces.
- Cats may avoid covering their poop due to discomfort, especially if they are experiencing pain or have been recently declawed.
Covering poop isn't always standard cat behavior. Wild cats bury their excrement primarily for two reasons: to hide their presence from predators and to show they aren't challenging dominant cats. Dominant cats often leave their waste exposed on grassy tussocks to make it more noticeable.
Thus, a domesticated cat might bury its poop if there's a dominant cat in the house. Still, burying excrement is a natural behavior. So, why might your cat not be doing it?
Pleasing Humans
Humans have encouraged the behavior in our pet cats, by selectively choosing (and breeding) the ones that are “clean.” Cats that leave their excrement uncovered for the world to admire are not abnormal—they’re just being cats.
If your kitty has always dug-and-covered as normal litter box behavior, and suddenly makes a statement with uncovered poop, ask yourself what else has changed. This may be the cat’s way of sending a smelly signal to other cats (or even a stray hanging around outside the window) that the territory is owned.
Declaring Territory
In the wild, dominant cats (including jaguars, leopards, lions, and tigers) that are competing for territory don't bury their feces, sending a message that they are declaring that spot as their own. A domesticated cat may choose to not bury their poop to let other cats—or their owner—know "I am here." Even if a cat has lived in the same place for a while, he may not feel it is his territory. The smell of their poop shows that particular cat's presence.
Natural Inclinations
Cats that choose not to cover, or leave a deposit outside the box, may simply be doing what comes naturally. Although burying feces is generally a modeled behavior from the mother cat, some cats actually never learn to do this. Separately, roaming kitties may use unburied waste as another form of marking.
Litter Box Issues
When it comes to litter boxes, size does matter. Maybe your cat's litter box is too small for them to turn around inside to bury the poop. And, as the saying goes, cats can be finicky—perhaps your cat doesn't like the feel of the cat litter, or the box is too dirty, and they would rather not spend any extra time in there. If you suspect one or both of these things could be true, give a new brand of litter a try, or upgrade to a larger litter box.
Medical Issues
There aren't any specific diagnoses that would cause your cat to not bury their poop, but if your cat is experiencing some kind of pain or discomfort—whether in their paws, while going to the bathroom, or just in general—that could deter them from spending more time in the litter box. Also, cats who have been declawed recently could choose to skip the burying process.
