Best match in this guide
Our top recommendation: Modkat XL
Modkat XL is the most adaptable pick because owners can begin with a familiar front opening and later test the top entrance. Its larger body is easier to justify than a compact cube when cat acceptance is still uncertain.

Decision first
Quick picks
The short answer
Choose the Modkat XL when you want the least risky transition because it can operate with a front or top entrance. The standard Modkat is the stronger compact choice for an average-size adult cat, while the Petmate Top Entry delivers the basic format at a lower price.
A top-entry box is primarily a containment design. High walls keep vigorous digging inside, and the lid gives paws another surface to cross before they reach the floor. In an apartment, the footprint helps only when the cat still has enough interior room to turn.
What we compared
| Decision factor | What to check |
|---|---|
| Access | Opening width, lid height, landing stability, and the cat’s willingness to jump. |
| Usable interior | The narrowest turning dimension matters more than the outside measurement. |
| Cleaning | A lid should open without requiring the entire box to be dragged out of place. |
| Tracking control | Textured walk-off area, lid perforations, and exit direction all affect loose litter. |
| Ownership cost | Liners, filters, replacement lids, and eventual plastic replacement add to the price. |
How we built the shortlist
We reviewed current US manufacturer pages for dimensions, entry configuration, included parts, cleaning access, and stated cat-size guidance. We favored models with documented support and a design difference that serves a real household constraint. If easy lid access matters more than floor space, compare the covered litter boxes for easy cleaning.
We did not measure tracking, long-term odor retention, or cat acceptance. Those outcomes depend on the individual cat, litter, cleaning routine, and room. Product positions are editorial fit judgments rather than laboratory scores.
Measure the cat and the jump
Start with the cat’s body length and normal jumping behavior. The opening must be wide enough for a comfortable descent, and the interior must allow a full turn without pressing against the walls. A confident jump onto a sofa does not automatically mean the cat will accept dropping into an enclosed toilet.
For a cautious cat, the Modkat XL’s front-entry configuration creates a useful bridge. The cat can learn the object and location before you ask it to use the top opening. Keep the familiar box available throughout that test.
When a top-entry box is the wrong tool
Skip this category if access is already difficult, the cat avoids covered spaces, or the only available location leaves the lid unstable. A large open pan with high rear walls can contain much of the same scatter without requiring a vertical entry.
Choose the entrance around the cat. Do not choose the cat around the entrance.
Pair the box with the right routine
Scoop at least daily, wipe the lid before its texture becomes packed with dust, and inspect reusable liners for trapped residue. Place a litter mat suited to the floor in the cat’s natural exit path rather than assuming the lid catches everything. If the cat begins hesitating, perching without entering, or eliminating elsewhere, restore the familiar setup and reassess the design.
Research shortlist
The picks in detail
Modkat XL
Best for: Adult cats that may need a choice between top and front entry
Modkat XL is the most adaptable pick because owners can begin with a familiar front opening and later test the top entrance. Its larger body is easier to justify than a compact cube when cat acceptance is still uncertain.
Why it stands out
- Converts between top-entry and front-entry use
- Larger interior than the standard Modkat box
- Swiveling lid opens for routine scooping
Watch-outs
- Premium price and proprietary liners
- Still requires a jump when used in top-entry mode
- Large exterior footprint for a covered box
Modkat Top-Entry Litter Box
Best for: Average-size adult cats in apartments where floor space matters
The original Modkat makes sense when a tidy footprint and an integrated walk-off lid matter more than maximum interior space. The brand limits it to cats up to its stated size guidance, so measure before buying.
Why it stands out
- Space-efficient square footprint
- Textured swivel lid returns loose litter to the box
- Includes a reusable liner and hanging scoop
Watch-outs
- Not the best fit for long or heavy cats
- Custom liner adds an ownership cost
- Top-only access offers no easier transition route
Petmate Top Entry Litter Box
Best for: Budget-focused homes that want a wide opening and dog resistance
Petmate provides the core top-entry benefits without a designer price. The attached lid and generous opening are practical, but the tall one-piece body still assumes the cat can jump comfortably.
Why it stands out
- Wide top opening with textured lid
- Tall walls help contain digging and spray
- Top entrance can make access harder for dogs
Watch-outs
- Official store availability can vary
- Plastic may retain scratches and odor over time
- No front-entry transition option
Arm & Hammer Top Entry Litter Box
Best for: Shoppers comparing mainstream top-entry boxes with familiar retail access
This is a sensible alternative when you prefer Petmate's Arm & Hammer line or find it locally. Buy it for the tall enclosure and hinged access, not for marketing claims about privacy or odor.
Why it stands out
- Fully enclosed walls contain scattered litter
- Hinged top supports routine access
- Mainstream brand with broad retailer presence
Watch-outs
- Similar limitations to other tall plastic boxes
- Not designed for mobility-limited cats
- Confirm opening size before purchase

Frequently asked questions
Are top-entry litter boxes good for every cat?+
No. They require a cat to jump onto the lid and lower into the box. Kittens, older cats, large cats with limited turning room, and cats with mobility concerns may do better with a low front entry.
Do top-entry litter boxes stop litter tracking?+
They can reduce scatter and give the cat a walk-off surface, but granules may still cling to paws. Litter texture, lid design, exit behavior, and a well-sized mat all affect the result.
Can I switch directly from an open box?+
A gradual transition is safer. Place the new box beside the familiar one, keep the litter consistent, and avoid removing the old box until the cat uses the new design reliably.
