As a cat owner, you’ve likely found yourself wondering why your cat seems to enjoy flinging litter outside the box. It’s a common issue that many cat owners face, and understanding why cats do this can help manage the mess.

Although it might seem like an annoying habit, there are several natural and behavioral reasons behind the litter-kicking phenomenon. Let’s dive into the reasons why cats kick litter everywhere and how you can manage it.

Instincts from Their Wild Ancestors

Cats have an innate instinct to bury their waste, which is rooted in their wild ancestry. Wild cats, such as their big-cat relatives, bury their waste to hide their scent from potential predators or prey. This survival mechanism continues in domestic cats. When your cat kicks litter around, it’s often an attempt to cover their waste to mark their territory or mask their scent, a behavior that still serves as a defense strategy even in a safe, indoor environment.

According to ELSpet, this natural behavior is deeply embedded in your cat’s instincts, even though your indoor cat doesn’t face the same threats as their wild counterparts.

The Size and Type of Litter Box Matters

One of the most common reasons cats kick litter out of the box is that the litter box might not be the right fit for them. Cats are picky about their space, and a litter box that is too small or shallow can make them dig more aggressively, leading to scattered litter. A larger litter box gives your cat the room they need to dig comfortably without kicking litter out.

Cats Are Territorial

Territorial behavior can also explain why some cats kick litter outside the box. Cats are naturally territorial creatures, and kicking litter can be a way for them to mark their space. This behavior is particularly common in multi-cat households, where one cat may feel the need to stake their claim over the litter box. As Dr. Rachel Geller, a certified cat behaviorist, explains on PetMD, cats may kick litter to spread their scent and mark the area as their own, especially if there’s a new pet in the home.

Health Issues Can Play a Role

If your cat suddenly starts kicking more litter than usual or seems to be in discomfort while using the litter box, there might be an underlying health issue at play. Conditions like urinary tract infections (UTIs) or arthritis can make it painful for cats to use the box. In these cases, excessive kicking or digging might be an attempt to alleviate the discomfort. As noted by Catster, if your cat’s behavior changes suddenly, a visit to the vet is recommended to rule out health problems.

Playing in the Litter Box

Another reason behind the litter-kicking behavior, especially in kittens, is playfulness. Some cats see their litter box as a playground. Digging and tossing litter around can be a fun activity, especially if the cat has a lot of energy or is not getting enough stimulation elsewhere. This behavior, while messy, is generally harmless. According to PetHonesty, kittens, in particular, are likely to kick litter out simply because they’re learning how to use the box, often in a playful manner.

A Dirty Litter Box

Cats are notoriously clean animals, and a dirty litter box can make them uncomfortable. If the box is not scooped frequently enough, cats may try to cover their waste more aggressively, which can result in litter being kicked out. Maintaining a clean litter box can reduce this behavior. As PetHonesty reports, regularly cleaning the litter box and ensuring it's kept fresh will make it a more inviting and comfortable place for your cat to use.

Choosing the Right Litter Type

The type of litter you use can also impact how much your cat kicks it out. Some cats are very particular about the texture and scent of their litter. For example, if the litter is too coarse or scented, it may cause your cat to dig more aggressively, leading to more mess. As Dr. Barri Morrison, a veterinarian reviewed on PetMD, explains, it’s crucial to experiment with different types of litter to find one that your cat prefers.

How to Reduce Litter Kicking

While you can’t completely eliminate your cat’s instinct to dig and bury their waste, there are several ways to manage the mess: 

• Use a larger litter box: A spacious box with high sides can reduce the amount of litter kicked out.
• Try a covered litter box: Some cats prefer the privacy of a covered box, which may also contain the litter better.
• Use a litter mat: These mats catch the litter that’s kicked out, making cleanup easier.
• Clean the litter box regularly: Frequent scooping ensures your cat has a clean environment, reducing unnecessary digging.

Cats kick litter for a variety of reasons, from instinctual behaviors to health issues. While it can be a frustrating problem for pet owners, understanding the underlying causes can help you manage and reduce the mess.

By making adjustments to the litter box, ensuring regular cleaning, and choosing the right litter, you can keep your home cleaner while respecting your cat's natural behavior. If the behavior persists or worsens, it’s always a good idea to consult with your vet to rule out any health concerns.
