A Modkat litter box is a smart pick if litter scatter or urine escaping over the sides is a problem. All three models have a seamless base, tall sides, and a reusable liner you rinse instead of scrubbing the box.
Each model suits a different kind of cat. The entry style and size are what decide which one fits yours.
Here’s how the Flip, Top-Entry, and XL compare, and which one to buy.
A Modkat litter box is a modern box with a seamless base and a reusable tarp liner. This review compares three covered models: the front-entry Flip, the original Top-Entry, and the XL, which offers both entry options.

What All Modkat Boxes Have in Common
The base is one seamless piece with tall walls. There are no seams for urine to leak through, which helps with cats that pee high or against the side.
Each box comes with a reusable liner made of tarp material. You lift it out, dump the litter, rinse it, and put it back. Modkat says each liner lasts up to three months.
Every model also comes with a hanging scoop that stores right on the side of the box, so it’s always where you need it.
Modkat Flip Litter Box
Why It Stands Out
The Flip is the easiest Modkat to live with. Cats walk in through the front instead of jumping in through the top. The magnetic lid has three positions: halfway open for quick scooping, fully open for changing litter, or closed for privacy.
The full-height TabFit liner clips onto tabs inside the box, so it stays put and keeps litter from getting underneath. It also comes with two bamboo charcoal filters, and it has over 4,500 ratings averaging 4.6 stars on Amazon.
Possible Downsides
The entrance sits 6.75 inches off the floor, so very young kittens or cats with stiff joints may find a lower box easier.
Best For
Most adult cats that prefer front entry, especially cats that kick litter or pee against the sides.
Modkat Top-Entry Litter Box
Why It Stands Out
This is the original Modkat, and it’s the best at keeping litter in the box. Your cat climbs in through the top, and the lid works as a grate that knocks litter off paws on the way out. Anything left on the lid falls back inside when you swivel it open.
It has the smallest footprint of the three, at 16 inches square, so it fits where bigger covered boxes won’t. It also keeps dogs out of the litter.
Possible Downsides
Modkat recommends this model for cats up to 12 pounds, so bigger cats are better off with the XL. We compare more styles in our top entry litter box guide.
Best For
Small to average-size, agile cats that kick litter everywhere, and homes where a dog keeps getting into the box.
Modkat XL Litter Box
Why It Stands Out
The XL comes with everything you need to set it up as top entry or front entry. You can also leave both entrances open, giving your cat two ways in and out. In top-entry mode, the lid catches litter like the original. In front-entry mode, a built-in step helps catch stray litter.
It includes both liners: Type C for top entry and Type D for front entry. The liners hang on hooks at each corner, so they stay in place. The swivel lid also lifts straight off for a full clean.
Possible Downsides
It’s the biggest Modkat, at 21 inches long, so measure your space first.
Best For
Large cats, homes with more than one cat, and anyone who isn’t sure whether their cat will take to top entry.
Which Modkat Should You Buy?
Start with your cat, not the box.
If your cat prefers to walk in, get the Flip or set up the XL as front entry. If your cat is young, agile, and a heavy litter kicker, the Top-Entry keeps the most litter off your floor. If your cat weighs more than 12 pounds, go with the XL.
Not sure your cat will accept top entry? The XL lets you start with front entry and switch later without buying a new box.
Modkat Liners: Which Type Fits
- Type A fits the Top-Entry: Modkat Type A liners
- Type C fits the XL in top-entry mode: Modkat Type C liners
- Type D fits the XL in front-entry mode: Modkat Type D liners
- Type F fits the Flip: Modkat Type F liners
Rinse the liner each time you change the litter and it’ll stay fresh for months. Modkat says you can also use the boxes without a liner. The liners just make cleanup easier.
Frequently Asked Questions
Is the Modkat litter box worth it?
Yes, if scatter, tracking, or side peeing are your main problems. The seamless base and tall liner keep all of that inside the box. Pair it with daily scooping and it stays fresh too.
Can big cats use a Modkat?
Yes. The Modkat XL is the one built for larger cats. Modkat recommends the original Top-Entry for cats up to 12 pounds.
How often do you replace Modkat liners?
Modkat says each liner lasts up to three months. Rinse it every time you change the litter, and replace it sooner if your cat scratches holes in it.
Can you use regular litter box liners in a Modkat?
Modkat liners are cut to fit each box. A plastic bag liner won’t stay up the tall walls the same way, and that’s where the seamless design does its job.
Which Modkat is best for senior cats?
The Modkat Flip or the XL in front-entry mode lets your cat walk in instead of jumping through the top. Both have raised entrances, so cats with mobility issues may do best with a lower-entry box.
