The best litter box for large cats is one in which the cat can navigate freely and not step on their own waste. As a rule of thumb, cats prefer large litter boxes so your large cat plus a large litter box is what you will need to consider. The litter box should be one and a half times the size of the cat when the cat is measured from the top of his head to the base of his tail.

Do you want an uncovered litter box or a covered litter box?

You don’t know? Which one is best? Is one better than the other?

From the cat’s point of view an uncovered litter box allows him to see who or what may be approaching the litter box. He can then escape if he feels threatened.
In contrast, apartment living or shared accommodation often means that space is a premium and a covered box may suit the living arrangements.

There is more information here about choosing an uncovered or covered litter box that will help you make a decision if you are unsure.

A Top Entry Litter Box For Large Cats

A top entry litter box for large cats needs to have the dimensions to suit the size of your cat. If you already have a rough approximation of the size you need it will be easier when you start looking.

Design features – Top Entry litter box

A reusable litter liner in the Modkat range of litter boxes.

Check the measurements of the box and the entry on the top of the box. It needs to be large enough for you cat to easily enter and exit.

Some boxes have a grate or textured finish on top to trap litter on paws.

Some boxes have a side hinge enabling the lid to open for easy cleaning.

How To Choose The Best Litter Box For Large cats

  1. First of all, decide whether you want a covered, uncovered or top entry litter box.

  2. Measurements – This is super important because there’s what we think of as a large cat and then there are cats that are really large like the Maine Coon and the Norwegian Forest Cat. Large takes on a different meaning. You will need the approximate measurements of your cat (length) and the measurements of the box that is under consideration.

  3. Where will the box be located? Consider the size of the room where the box will be located. A jumbo litter box designed to fit into a corner is perfect if you are low on space but have a large cat.
    If space is tight the box measurements are important. Avoid the scenario of having the box arrive only to discover that it doesn’t fit into the space you had allocated.

  4. Cleaning the box. Will it be easy to scoop? Does the box have handles? Are the handles built in to the box? Built in handles are desirable in our opinion, one less thing to break. If there are no handles will the box be easy to pick up when needed to empty the litter?

  5. The age of your cat. Our cat is elderly and jumping into a box with high sides is not an option although sometimes he surprises us. Never underestimate a determined kitty. Climbing a stairway entry is more his style as in the Petmate Litter Dome.

What’s all the fuss. I’m not that large!

About Measuring – Cat? Box? location?

Yes, you do need to measure the cat and the box and the intended location of the box.

I don’t know about you but it can be hard to visualize measurements especially once you have read through several lists of different measurements.

It is a quick and simple matter to measure which just takes a few minutes. Mark out the measurements of the box on some newspaper to get a good visual of how big the box really is.

It is worth spending those few minutes measuring particularly if the intended space for the box is somewhat limited or restricted by other fixtures.

Even taking the measurements into account, it is difficult to say 100% that the box will be suitable for your large cat. The dimensions may be okay but cats assume different positions when doing their business so there is no one size fits all. I never believed any of that one size fits all nonsense. Just like people cats come in lots of different sizes.

Research also suggests that bigger is better. One of the findings from this study indicated that larger litter boxes were preferable for all size cats not just large cats.

Is Your Large Cat Also A Digger And Flinger?

If your cat is large and a digger and flinger you will need a large box with high sides to stop litter being flung around like a snow storm.

Thank goodness you are not a digger and flinger dear! Sounds dreadful!
