Why Does My Cat Bury Toys in the Litter Box? (And How to Stop It)

There is nothing quite as frustrating—or gross—as going to scoop the litter box and finding your cat's favorite plush mouse half-buried in the sand. Your first thought might be that your cat thinks the toy is garbage, or that they are protesting a dirty box. But your cat isn't burying toys in the litter box because they hate them. They are doing it because of a biological instinct called "caching." In the wild, cats bury their prized catches in areas that smell strongly of themselves to hide the food from scavengers. Your indoor cat views the litter box as the most heavily scent-marked, secure "vault" in the house to hide their favorite "prey."

What is Feline Caching Behavior?

To understand this messy habit, you have to look at how cats survive in the wild. Felines are unique because they occupy the middle of the food chain—they are fierce predators, but they are also small enough to be prey for larger animals. If a wildcat catches a large meal that they can't finish right away, leaving it out in the open will attract dangerous scavengers.

To protect themselves and their food, they engage in "caching." They will drag the kill to a secluded area and bury it under leaves or dirt to mask the smell. When your indoor cat "kills" a small plush toy, their predatory brain kicks in. Even though there are no coyotes in your apartment, they still feel the overwhelming urge to hide their catch.

Why the Litter Box Specifically?

If caching is about hiding things, why choose the bathroom? It all comes down to feline territorial markers. A cat's world is defined by scent. The litter box is the epicenter of their territory because it smells unequivocally like them.

By burying their toy in the litter box, they are essentially surrounding their valuable prize with their own scent barrier. It is their way of saying, "This belongs to me, and it is hidden in the safest, most clearly marked area of my territory." This is the exact same biological instinct that drives some cats to put toys in their water bowl, as water is another "safe" zone that masks scent.

Is It Safe to Let Them Keep Doing This?

While the intention behind the behavior is instinctual and natural, the outcome is highly unhygienic. You should not allow your cat to continue burying toys in their litter box.

Litter boxes are full of dust, ammonia, and fecal bacteria. If your cat buries a toy, digs it up the next day, and begins chewing on it or carrying it around in their mouth, they are directly ingesting that bacteria. This can lead to gastrointestinal upset and oral hygiene issues. The behavior must be stopped, not accommodated.

How to Stop Your Cat From Putting Toys in the Litter Box

You cannot train a biological instinct out of a cat. You cannot yell at them to stop caching, and they will not understand why you are throwing their favorite toy away. Instead, you must manage their environment using these steps.

1. Stop Playing Near the Bathroom

If you wave a wand toy right outside the bathroom door and let them "kill" the attachment on the bath mat, the closest hiding spot is the litter box. Move your intense play sessions to the living room or bedroom. The further they have to carry the toy to reach the litter box, the more likely they are to get distracted and drop it along the way.

2. Upgrade to Un-Carriable Toys (The Hardware Fix)

The simplest and most effective way to stop a cat from putting toys in the litter box is a hardware fix: give them toys that are physically impossible to carry. If they only cache small, lightweight plush mice, remove those toys from the rotation entirely when you are not actively supervising them.

3. Keep the Litter Box Immaculately Clean

While scent is the main driver, a dirty litter box actually encourages digging behavior. If the box is full, your cat will spend more time in it trying to cover their own waste, and the toy in their mouth may simply get dropped and buried in the process. Scoop daily to minimize their time spent rearranging the litter.

The Best 'Un-Buryable' Cat Toys to Solve the Problem

If you are tired of throwing away soiled toys and trying to figure out how to clean cat toys that have been buried in clay dust, it is time to upgrade your cat's toy box. By switching to toys that cannot be carried, you completely eliminate the hygiene risk while still satisfying their need to play.

The ultimate solution is the KittySpin. Because the ball is securely trapped inside the circular track, your cat can bat, stalk, and "hunt" the ball all day long. But no matter how hard they try, they physically cannot pick it up and carry it to the bathroom.

If your cat requires a physical target to bite and bunny-kick to satisfy their hunting cycle, swap the small plush mice for the Floppy Fish. It is large and heavy enough that it is incredibly difficult for most domestic cats to drag across the house and hoist over the lip of a litter box.

For independent chase play, the Interactive Rolling Ball is an excellent choice. Its smooth, hard, spherical surface makes it very difficult for a cat to get a firm enough grip to carry it long distances in their mouth, keeping it safely on the living room floor where it belongs.

Frequently Asked Questions

Why did my cat just start putting toys in the litter box?

If this is a new behavior, it is often triggered by a perceived threat to their territory. A new pet, a new roommate, or even a change in your work schedule can make your cat feel insecure. Caching toys in the litter box is their way of aggressively protecting their favorite items when they feel their territory is unstable.

Should I wash or throw away toys found in the litter box?

If it is a hard plastic toy, you can wash it thoroughly with hot water and dish soap. If it is a soft plush or cloth toy, the fabric will absorb urine and fecal bacteria deep into the stuffing. It is much safer for your cat's health to throw cloth toys away rather than trying to sanitize them.

Why does my cat put toys in their water bowl instead?

Putting toys in the water bowl is another form of caching. In the wild, water washes away the scent of a fresh kill, hiding it from other predators. Your cat is simply using the water bowl as a different type of "safe" to hide their prey.

Is my cat putting toys in the litter box because they are bored?

Not necessarily. While boredom causes many behavioral issues, caching is a specific predatory instinct related to hunting and resource guarding. However, a bored cat will hunt their toys more often, which leads to more opportunities for caching.

Can a dirty litter box cause caching behavior?

A dirty box won't cause the caching instinct, but it can make it worse. If the box is too full, your cat has to spend more time digging to find a clean spot. If they happen to carry a toy in there while doing so, the toy is more likely to get buried in the mess.
