Modkat Top Entry Litter Box Review: Pros, Cons & Key Features

⚡ Quick Verdict

📋 How We Evaluated

We scored these on four things: how well the lid design actually traps litter, how the base holds up against leaks and spraying, how fast the daily scoop-and-clean routine goes with the swivel lid, and whether the liner system is worth the recurring cost. Fit for your specific cat, size, age, jumping ability, matters more than any single number below.

Modkat vs. Modkat XL: Which One Do You Actually Need?

Both boxes use the same core idea, a swivel lid that doubles as a walk-off mat. The difference comes down to size and entry flexibility, not build quality. Here’s the side-by-side:

If your cat is under roughly 12 pounds and you’re not planning to add a second cat, the original does the job for less money and less floor space. Go XL if you’ve got a Maine Coon, a Ragdoll, more than one cat sharing the box, or a cat whose jumping ability might decline as it ages, since the XL is the only one that converts to front entry.

Entry Type	Top or Front
Liner Included	Type C and D
Material	Plastic
Color	White

What We Found

The XL exists for one reason: bigger cats need more room to turn around, and the standard Modkat just doesn’t give them that. This model switches between top and front entry, which matters more than it sounds. A young cat that happily jumps in through the top today might not want to in five years. Both Type C and Type D liners ship in the box, so you’re covered whichever mode you set it up in.

The swivel lid works the same as the original, one hand, no wrestling with a hood. In front-entry mode, a built-in step catches litter before your cat steps onto the floor, though it won’t stop everything. The extra footprint is the real tradeoff here, and it’s worth measuring your space before you order.

This is a heavier, sturdier unit than the standard box, which is exactly what you want for a large cat that jumps and lands with force. It comes with a sifting scoop and both liner types included, so there’s no separate purchase needed to get started.

Who It’s For

Owners of large breeds like Maine Coons or Ragdolls should start here, not with the standard size. It also fits multi-cat households that need one larger box instead of two smaller ones. And if your cat is aging and might lose confidence jumping, the front-entry option means you won’t need to replace the whole box later.

It costs more than the standard model. That premium buys flexibility, not just size, so weigh it against whether your cat actually needs the extra room now.

What We Found

The Modkat Top-Entry Litter Box is the model most people mean when they say “Modkat.” The lid does double duty as a lid and a walk-off mat, catching stray granules on the way out. The base is one seamless piece with high walls, which matters if your cat sprays while standing, since there’s no seam for urine to find.

The reusable liner is the part people either love or resent. It holds up for about three months of regular use before it needs replacing, and buying replacements is an ongoing cost you should factor in up front, not discover later. The payoff is a swivel lid that opens with one hand, so scooping takes seconds instead of lifting a whole hood off.

Inside, there’s enough room for an average-sized cat to turn and dig without feeling cramped. It ships with a sifting scoop that actually fits the box’s shape, which sounds minor until you’ve used a scoop that doesn’t match.

Who It’s For

This suits apartment dwellers and anyone tired of finding litter granules on hardwood or carpet three rooms away from the box. It works best for cats under roughly 12 pounds that don’t mind a vertical jump to get in.

Skip it if your cat has joint issues or hesitates at anything higher than a low step. The jump height is the one real barrier here, and no amount of design polish changes that.

Entry Type	Top or Front
Liner Included	Type C and D
Material	Plastic
Color	Gray

What We Found

Same XL box, different color. Gray hides scuffs better than white does, especially if you’re not cleaning the exterior weekly. Everything else carries over: the top-or-front entry switch, both liner types in the box, and the extra interior room over the standard size.

The swivel lid mechanism is identical to the white version, and the built-in step for front-entry mode still helps catch litter, though not perfectly. Build quality feels the same across colors, so this isn’t a case of the gray unit being a downgrade. Pick it based on your decor, not your expectations for performance.

If you already know you want an XL, the color choice comes down to what blends into your laundry room or bathroom.

Who It’s For

Owners of large cats who want the same flexibility as the white XL but prefer a color that shows less dust and fewer scratches over time. It’s a good match for neutral-toned bathrooms or laundry rooms where a bright white box would stand out.

Everything else about who should buy this matches the white XL: large breeds, multi-cat homes, or cats that might need front-entry access down the line.

Entry Type	Top
Liner Included	Type A
Material	Plastic
Color	Black

What We Found

The black version of the Modkat Top-Entry Litter Box is mechanically the same box as the white one, just in a matte finish that hides scratches better than either the white or gray option. The lid still traps debris on exit, the base is still one seamless piece, and the interior room is unchanged.

The reusable liner and swivel lid work exactly as they do on the white model. This one ships with a sifting scoop and, on some listings, a small interactive toy. Don’t buy it expecting anything functionally different. Buy it because black fits a darker room better than a white box would.

One thing worth flagging: a dark surface shows dust and litter dust more visibly than white does under bright light, which is a minor tradeoff for the better scratch-hiding.

Who It’s For

Anyone who wants the standard Modkat’s performance but doesn’t want a white box sitting in a dark-themed room. It suits the same cat profile as the white version: average size, comfortable jumping, single-cat households.

If your cat struggles with mobility or you need multi-cat capacity, the standard size box won’t solve that regardless of color. Look at the XL instead.

Entry Type	Top
Liner Included	Type A
Material	Plastic
Color	Gray

What We Found

The gray standard-size Modkat rounds out the color options without changing anything under the hood. Same top-entry lid, same seamless leak-proof base, same Type A liner. It’s the least common color of the three, but functionally you’re not giving anything up by choosing it.

The swivel lid opens the same way, the interior offers the same turning room for an average cat, and the included scoop and toy match the other standard-size listings. If white feels too stark for your bathroom and black feels too heavy, gray splits the difference.

This is a reliable, no-surprises pick if you’ve already decided on the standard size and just need a color that fits your space.

Who It’s For

Owners who want the standard Modkat’s litter-trapping performance with a neutral color that won’t clash with existing decor. Good fit for the same single, average-sized, confidently-jumping cat as the white and black versions.

If space or multi-cat capacity is the concern rather than color, this won’t solve that. Move up to the XL instead.

Modkat Liner Types Explained

Modkat doesn’t use one liner across its whole lineup, and buying the wrong replacement is the most common complaint we see. Here’s how the types map to each box:

• Type A fits the standard-size Modkat Top-Entry box (top entry only). This is the liner you’ll be replacing roughly every three months on the original model.
• Type C fits the Modkat XL in top-entry configuration.
• Type D fits the Modkat XL in front-entry configuration.

Check your box’s model and entry mode before ordering a replacement liner. A Type A liner won’t fit an XL, and a Type C won’t fit the standard box. If you’re not sure which one you have, the packaging or the listing your box shipped from will list the letter.

What to Look For Before Buying

The right litter box changes your daily routine, not just your floor. Weigh your cat’s size, age, and habits before you buy, since the wrong fit means either a stressed cat or a box that gets ignored.

Check Your Cat’s Age and Mobility

Top-entry boxes ask a lot of a cat’s joints. Older cats or ones recovering from injury may avoid a box they’d have used fine at three years old. If you’re not sure, watch how your cat handles jumping onto furniture at similar heights. If they hesitate there, they’ll likely hesitate here too, and a front-entry option like the XL becomes worth the extra cost.

Factor In the Real Cost of Maintenance

A swivel lid saves time daily, and that matters more than it sounds like over a year of scooping. But reusable liners aren’t free forever. Budget for a replacement roughly every three months, and check whether the specific model you’re buying uses a proprietary liner or something more generic. Modkat liners are proprietary, so factor that into your long-term cost, not just the sticker price.

Measure Your Space Before You Commit

Top-entry boxes trade floor footprint for vertical height. That’s usually a win in small apartments, but the XL still needs more square footage than the standard box. Measure the spot you’re planning to use, including clearance for the lid to swing open, before you order.

Check Build Quality and Seams

Seamless plastic bases prevent leaks better than boxes assembled from multiple pieces, especially for cats that spray while standing. Look for a base that’s a single molded piece rather than a bin with a separate lid clamped on. A sturdy base also matters for larger cats, since a flimsy one can tip or flex under their weight when they jump in.

Frequently Asked Questions

Can senior cats use a top-entry litter box?

Some can, many struggle. Cats with arthritis or joint pain often avoid the jump required for top entry. If your cat is a senior, the Modkat XL’s front-entry mode is the safer choice, or consider an open pan instead.

How often should I replace the Modkat liner?

Around every three months with regular daily scooping. Check for tears, thinning, or odor that soap and water no longer clear before that mark, since heavy scratchers wear through liners faster.

Which liner does my Modkat need?

Type A fits the standard top-entry box. Type C fits the XL in top-entry mode. Type D fits the XL in front-entry mode. Match the letter to your model before ordering a replacement.

Does the top-entry design actually stop litter tracking?

It cuts it down significantly, since the lid works as a walk-off mat that traps litter from paws on the way out. It won’t eliminate tracking completely. Litter clinging to fur past the paws still ends up on the floor sometimes.

Is the Modkat XL worth the extra cost over the standard box?

If you have a large-breed cat, multiple cats, or a cat whose jumping ability might decline, yes. If you have one average-sized, healthy cat and limited floor space, the standard box does the job for less money.

How do I clean a Modkat litter box?

Swivel the lid open and scoop daily, same as any box. For a deep clean, pull the liner out, wash the seamless base with mild soap and water, let it dry fully, then reinsert the liner. Avoid harsh chemicals, since strong scents can put a cat off using the box at all.

Will a top-entry box help with a cat that sprays or pees standing up?

Yes, this is one of the strongest use cases for Modkat’s design. The high, seamless walls contain spray far better than an open pan, and the lack of a seam at the base means there’s nowhere for urine to leak through.

Can I use clumping litter in a Modkat box?

Yes. The design works with standard clumping clay litter as well as lighter alternatives. Heavier clumping litter tends to sift through the lid’s holes a bit less than fine-grain litters do, which some owners prefer.

🎯 Final Verdict

For most single-cat households, the Modkat Top-Entry Litter Box is the right call. It cuts down tracking more than any front-entry design can, the swivel lid keeps daily scooping to seconds, and the seamless base handles spraying without leaking.

If your cat is large, you’re running a multi-cat household, or you want the option to switch to front entry as your cat ages, spend the extra money on the Modkat XL. Skip both if your cat has mobility issues, since no color or configuration changes the jump height requirement on the top-entry mode.

Whichever size you land on, budget for a replacement liner roughly every three months and match the letter, A, C, or D, to your specific box.
