Need to Know The Best Litter Box For Large Cats?

Why Choose A Large Litter Box?

A large cat needs a large litter box, plain and simple. In fact, as a rule of thumb, cats prefer large litter boxes and a cat will be more likely to use the litter box if they are not stepping on their own waste.

An Uncovered Box Or A Covered Box?

One issue with an uncovered box is that you could end up with more litter outside of the box than in the box, however if your cat has deemed that an uncovered box is the way to go there are some uncovered boxes with very high sides.

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

How To Choose A Large Litter Box

You ​may already know if you want a covered or uncovered box so once that decision is made the next thing is check the dimensions.

Litter boxes called jumbo or giant are the biggest ones for obvious reasons and you should be able to find what you need but still check the measurements.

Your large cat needs space to move around and it may be that you need to source a box or storage bin that you can use as a cat litter box.

  • Decide on a covered or uncovered litter box. We have done both. ​With new and improved designs ​hitting the market all the time, it may well be that you change the type or style of box that you have always bought.
  • Measurements - This is super important because there’s what we think of as a large cat and then there are cats that really are large like Maine Coon and Norwegian Forest Cats, (love those big kitties) so large takes on a different meaning.

  • 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.

Five Reviews Of Litter Boxes For Large Cats

With so many choices of litter boxes ​and many different features, it can be confusing knowing which one will be suitable for your household and kitty. 

Catit Jumbo Hooded Cat Litter Pan

Catit Jumbo Hooded Cat Litter Pan - Warm GrayCatit Jumbo Hooded Cat Litter Pan – Warm Gray

Does your kitty fit in this box?

These are the measurements. When assembled the measurements are 22L” x 20”W x 18”H.
The door opening is 10.4” x 9.6”.

It does have a hood as can be seen in the photo. The top can be unclipped for easier cleaning however the opening is also a decent size so that it is possible to scoop the box without actually removing the door.

The clips are not needed for everyday use, only if moving the box so it’s a pretty easy matter to just lift the top off for cleaning. This is a big box.

For those kitties who don’t like doors, the  door can be removed or flipped up to sit on top of the box.

It has a carbon filter (you can see it on top of the box) to help remove odors.

The top is light colored on a darker base to camouflage any stains.

Petmate Giant Litter Pan

Petmate 22040 Giant Litter Pan, Bleached LinenPetmate 22040 Giant Litter Pan, Bleached Linen

The measurements are: 34.7″ x 19.8″ x 10″ however you can see in the image that there are two pockets at the front, so the size of the litter part of the box is approximately 27″ x 17″.

This is a big box! I have seen a photo of a five year old child lying in a box like this.

It pays to have a tape measure handy so you can see the size and how it “really” looks. Use the measurements to draw the size of the box onto paper (newspaper) to give a clearer idea of the size of the box.

What are the pockets for? Well the obvious answer is the scoop or scoops but also spray cleaner or anything else you want to keep handy.

The length of this box really does put it into the giant category for large cats. It won’t stop litter escaping the box.

The box can hold 30 lbs of litter and is suitable for multiple cat households

This is a very sturdy product, very large and suitable for very large kitties.

Petmate Booda Cleanstep Litter Dome

Booda Dome Cleanstep Cat Box, TitaniumBooda Dome Cleanstep Cat Box, Titanium

The stairway entry and exit means that the litter is largely confined to the box so a big plus from the litter cleaning patrol.

The measurements are 20″ x 24″ x 19″.

There are liners available for this model, however like any cat litter box, they do not need to be used if this is your preference.

It has a charcoal filter to help with odor control.

I know it is a cat litter box, but the design plus the practicality is gorgeous, definitely the Home Beautiful of cat litter boxes.

This is important if space is limited and the litter box is in the living area.

This box fits into the large litter box category.

IRIS Open Top Cat Litter Box with Shield and Scoop

IRIS Open Top Cat Litter Box Kit with Shield and Scoop, WhiteIRIS Open Top Cat Litter Box Kit with Shield and Scoop, White

The measurements are – 19″ x 15″ x 11.75

The litter shield is removable which makes it super useful for cleaning and emptying the litter.
The height of the shield will help prevent litter being spread around when kitty is digging, flicking or turning around in circles.

It comes with a scoop included that clips to the inside of the box, so there is no hunting around for the scoop.

Where the top half of the box clips to the lower half of the box, there is the possibility that if your cat is a high pee-er (sorry not a word, I know) there may be pee spillover where the shield and the box meet.  A solution for this is to lift the shield and tuck a paper towel between the shield and the lower part of the box. Then it is just a matter of replacing the paper towel as needed.

If your cat is not a high pee-er this won’t be an issue.

The interior of the box has a high shine (polished) which helps with cleaning

Petphabet Jumbo Hooded Cat Litter Box

Petphabet Jumbo Hooded Cat Litter Box, Extra Large, Light BluePetphabet Jumbo Hooded Cat Litter Box, Extra Large, Light Blue

The measurements of this box are – 24.8″L x 20″W x 16.5″H. The door opening size is 8.2” X 7.8

It has a high back to reduce spillover from high pee-ers.

This box does not have a gate or door so there is nothing to flip backwards and forwards.

The top is easily removable for cleaning and clips on and off. This is suitable for any age cat as it is easy for the cat to step into the box because of the wide entrance.

The box uses advanced plastic technology for odor blocking and antimicrobial protection.

The surface is non stick (hmm sounds like cookware) but this actually makes cleaning easier.

About Measuring...The Cat? The Box?

​Yes, you do need to measure both, the cat and the box to have some idea of the box you need for your large kitty. 

I don't know about you but it can be hard to visualize measurements especially when you have read through a list of them.  

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

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. 

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. 

​Some Tips To Encourage Kitty To Use The Litter Box


If you want a hooded box we recommend the Catit Jumbo Hooded Litter Pan because the size of the box is large and the door opening is large to suit large cats.

Another bonus is the ease of cleaning because of the large entry. The entry door being able to stay flipped up is also a useful feature. Everything is geared towards large in this box.

If you want an uncovered box, definitely the Petmate Giant Litter Pan is our recommendation. This is not just a large box, this is a ​gigantor box.

To get one larger you would need to make your own. The two pockets at the front are an extra handy feature for a litter scoop or spray cleaner. Just line the pockets with a plastic or paper bag to make cleaning faster. ​Measuring 27" x 17"for the actual part of the box that holds litter, ​makes this a big, big box. ​.
