Litter Boxes for Large Cats: 3 Solutions

Est. read time: 6 min.

It’s no secret that cats are picky about their litter boxes. Getting your cat's litter box situation just right requires Goldilocks-level precision: not too big, but not too small; not too hidden, but not too public; not too covered, but not too open; not too this, and certainly not too that.

Add to your calculation the need to please a large breed or overweight cat, and the task becomes even more challenging. Never fear! We have narrowed down the most important things to consider when looking for litter boxes for large cats.

Why are large cats picky about the litter box?

Cats may love squeezing themselves into boxes or curling up in tight quarters, but when it comes to the litter box, it’s a very different story. Larger cats simply don’t fit comfortably in average-sized litter boxes. They need more space to turn around and stand up. They need to enter and exit without touching walls or ceilings. They simply need a litter box that fits them if we're to expect them to use it reliably.

When you have a large cat breed—or even just a cat with some extra padding—you’re going to have to pay special attention to their litter box needs.

Think big

When selecting a litter box for a large cat, the general idea is—you guessed it—big cats need big litter boxes. You may have to eke out the space for its larger footprint and possibly pay a little more for a larger kitty-commode, but those minor inconveniences are well worth it to prevent your large cat from avoiding an undersized litter box and choosing to go elsewhere.

On a budget? While there are many oversized litter boxes out there, from traditional to automatic, you can also DIY with a little creativity.

If you have an especially large cat or multiple large cats, you may want to use plastic containers as litter boxes. Large storage bins and under-bed storage containers make for cost-effective litter boxes. If you have a litter-kicking kitty, buy a container with high walls (clear plastic is best) and cut out an entryway; otherwise, choose a large, low-walled container, fill it with litter, and there you have it: a litter box that's juuust right.

Choose a more open litter box

You may prefer a covered litter box to contain smells and keep the clumps out of sight, but your large cat probably doesn't. Large cats tend to prefer litter boxes that feel open or airy, where they can enter and exit with ease, turn around comfortably, and use the box without feeling confined.

Try self-cleaning solutions

Larger cats make larger messes, so you might hope to use a self-cleaning litter box that does the work for you. The catch? They have to fit! There are only a few automatic or self-cleaning litter boxes out there made to fit large or overweight cats.

In addition to noting your cat's measurements, shop around until you find a self-cleaning litter box that’s proven to be a successful solution for large cats. Again, choose an option that has an open feel, so your cat doesn't feel confined and uncomfortable.

Use multiple litter boxes

Don’t forget the golden rule for multiple cat households: Generally, you want the number of litter boxes to equal the number of cats, plus one. For a three-cat household, for example, you should maintain four litter boxes. If you have a self-cleaning litter box, you can get away with fewer litter boxes since it cleans itself automatically (and is therefore more attractive to use).

When one or more of your cats is larger than average, having enough appropriately-sized litter boxes is even more important. You don't want to create a situation where all of your larger cats are forced to use one large litter box; give your larger cats plenty of options to keep them happy (and avoid a mess).

The best litter boxes for large cats
