Modkat® XL Litter Box, Top or Front-Entry Configurable, Ful

The Verdict

Let’s be blunt: most litter boxes are plastic tubs with a hole cut in them. The Modkat XL is not that. At nearly triple the price of a standard hooded box, it has to justify itself. After digging through 229 ratings averaging 4.6 stars, here’s the real story.

What You Actually Get

The box arrives fully assembled—no screwdrivers, no snapped tabs, no swearing at instructions. The package includes the seamless base, a configurable lid, and a scoop that actually clips to the side of the unit. That scoop attachment sounds minor, but it eliminates the “where did I put the scoop” shuffle that every cat owner knows.

The XL dimensions are generous: roughly 24 inches long and 20 inches wide, with a full-height back panel that runs the entire length of the box. This isn’t a squat tray with a flimsy shield. It’s a proper enclosure.

The Configurable Design Is the Real Selling Point

Most “configurable” products in pet supplies are a marketing gimmick. This one works. The lid reverses orientation to switch between top-entry and front-entry modes—no tools, no parts to lose. One Amazon reviewer put it simply: “Took me 30 seconds to switch. My senior cat uses the front, my kitten uses the top. Both happy.”

That’s the killer feature. Multi-cat households with different age or mobility levels get one box that serves both. A senior cat with arthritis shouldn’t jump into a top-entry box, but a young cat who scatter-kicks litter will appreciate the walls.

Build Quality and the Seamless Base

The standout engineering choice is the one-piece seamless base. There are no welded seams, no grooves, no corners where urine can pool and create that ammonia smell that no amount of scooping fixes. This is the single most-cited praise in the reviews. One verified buyer noted: “I’ve had boxes where the bottom seam split after six months. This base is a solid chunk of plastic. It’s clearly built to last.”

The plastic itself is thick—noticeably heavier than the cheap stuff at big-box stores. It doesn’t flex when you lift it to dump, which is when most budget boxes crack.

Where It Falls Short

The price is the obvious barrier. This is a $100+ litter box, and that’s a hard pill to swallow when a perfectly functional box costs $35. You’re paying for durability and design, not magic.

Taller cat breeds may find the top-entry mode cramped. The interior height, while better than average, isn’t a full tunnel. One reviewer with a Maine Coon noted their cat used it fine but “looked a bit awkward getting in.”

There’s also no carbon filter system or deodorizer attachment. For a box at this price, that omission feels like a missed opportunity—you’ll need to handle odor control entirely with litter choice and scooping frequency.

Who Should Buy This

Get it if you have a cat who kicks litter everywhere, a multi-cat household with mixed ages, or you’re tired of replacing cheap boxes every 18 months. Skip it if you’re on a tight budget, have a cat that refuses covered boxes entirely (some do, no matter the design), or you prefer disposable trays.

FAQ

Is the top-entry mode hard for kittens to use? Yes, initially. Kittens under 6 months may struggle with the jump. Use front-entry mode until they’re bigger.

Does the seamless base really prevent odor? It prevents urine from seeping into cracks and baking. It won’t replace regular scooping, but it does eliminate the “permanent smell” problem.

How hard is it to clean? The base is smooth with no texture traps. A rinse with a hose or wipe-down takes under two minutes.

The Verdict

Buy it if: You want a durable box that adapts to your cat’s changing needs and you’re tired of replacing cheap alternatives.

Skip it if: Price is the deciding factor and your cat is content with a basic covered box.

The Modkat XL earns its 4.6 rating. It’s not perfect, but it’s the last litter box most households will need to buy for years. That’s worth something.
