An extra large, open top litter box will ensure that your large cat has enough space when using the litter box.
An extra large litter box will also help keep the litter box clean, rather than the litter being kicked out onto the floor.
These litter boxes all have an open top. An open top makes the litter box easily accessible for cleaning and for the cat to enter and exit.
The measurements of each box are given below. It can clearly be seen that all of these open top litter boxes are large. It really depends on the measurement of the space you have allocated to the litter box.

This litter box is called Giant because of its size. There is also an open top litter box called Jumbo, however the Giant is larger. The measurements are 25.56 x 18.3 x 10.02 inches.
This box is blue or blue!
Pros
It has sloped sides so that the front edge is lower (6 1/2 inches approx) which is good for older cats to enter and exit the box easily.
The edges are rimmed which helps when lifting the box.
Cons
The front edge may be too high for kittens. In this case a booster step would work until the kitten grew.
Some cats pee over the lower front edge.

2. Frisco High Sided Cat Litter Box – Extra Large 24-In
The surface is polished (the shine can be seen in the image), making it easy to clean.
The open top and lower front make it easy to scoop and keep clean.
With a 10 inch rear wall, this box has had a good reaction from owners with high-peeing cats, unless they turn around and pee through the entrance. In that case, place the entrance facing a wall.
The plastic is BPA free and the box can be recycled.
There is no lid for this box. The box is sturdy and thick plastic,
It comes in two colors: gray and navy. One helpful review commented that the navy shows the dust from the litter, so if that is going to annoy you, gray is a better color choice.
Another excellent suggestion is to use a marker to draw a line on the box at the three-inch mark, so that you can see at a glance how much cat litter needs to go into the box.
With very large litter boxes, the size can cause us to overfill the box, when it is absolutely not necessary.
Pros
At 24 inches long, it has the tick of approval from a Maine Coon owner. The cat also happens to be a high pee-er.
This box has positive reviews regarding litter actually staying in the box and is recommended even if you do not have a super large cat.
Cons
The navy color shows the dust.
The cat may turn around and pee through the entrance.
Specifications
The measurements for the box are 24 X 18 X 10 inches. The height for the cat to step into the box is 6 inches. The box has a 10 inch rear wall. There are two color choices, gray and navy.

This may be the first time you have considered a stainless steel litter box.
This litter box come with a removable enclosure which makes the sides higher. The link on this page is for the litter box and the enclosure, however both can be purchased separately.
We have become so conditioned to plastic of one type or another. However stainless steel does makes perfect sense.
Often our pets already have food bowls and water bowls that are stainless steel.
I like the way I can get them super clean with a bit of a scrub when needed.
Plastic can absorb odors over time. Stainless steel will outlive plastic many times over.
Not contributing to landfill is a win win for me.
Size wise, it is not quite as large as the Petmate Giant.
Pros
Optional surround that makes the sides of the box higher.
Plastic can discolour and absorb odors over time. Stainless steel is a good alternative.
Cons
The enclosure sits on top of the box, however some cat owners find that it really needs to be secured firmly to work properly.
Specifications
The measurements of this stainless steel litter box are 23.5 x 15.5 x 6 inches.

tips to help with choosing the best box for your large kitty
1. Measure the cat from his cute little nose to the base of his tail (not the end of his tail)
2. Have the measurements at hand of all the boxes you think may be suitable.
3. Measure the location where the box will be placed. If space is tight, make a paper pattern of the dimensions and fit it into the allocated space. Does it fit?
