Key Features of the top entry

- Enclosed design: Maintains cat privacy, offers pet odor control, and doubles as a dog proof litter box for multi-pet homes.
- High sided box: The tall, sturdy walls prevent spraying and contain all messes within the easy clean litter area—no more scattered debris.

Real-World Performance Testing
Independent reviews confirm the top entry performs impressively at keeping tracked cat litter in check. Lab testers with multiple cats found that the grooved lid catches over 80% of granules on exit—a standout among high sided models. Most users report a 75%+ reduction in floor mess compared to standard covered litter solutions.
This product’s rigid plastic build offers stability when filled with 3+ inches of cat litter, though it may wobble if not bottom-heavy. Its pet odor control is solid, averaging 4 out of 5 stars based on long-term testing at Cats.com. The covered litter box eliminates easy dog access, making it an excellent dog proof litter box for curious homes.
Cleaning is simple: pop the lid with side buttons, scoop, and reattach. However, the included scoop is smaller than premium alternatives, so some users upgrade. Removing refuse is straightforward, and the open top makes refilling and maintenance fast for busy pet parents.

Note: This setup may not suit very large or elderly cats who struggle with jumping. If you need more space or low entry, explore our DIY cat wall shelves guide for alternative cat-friendly solutions.
How It Compares to Alternatives
Compared to the Modkat XL and Petmate Top Entry, this product offers comparable litter tracking reduction and cat privacy with a more budget-friendly price. The Modkat XL features a more robust construction and a larger entry, which is better for very large cats but can cost double. Petmate’s version uses thinner plastic and doesn’t lock as securely, giving IRIS USA’s modern cat box a lead in stability for its price tier.
One trade-off is the lid’s fit—it locks but requires firm reseating, which some users find less convenient than the flip-top system of premium models. Still, this model is highly rated for value, wellness features, and modern home appeal.
Who Should Buy This Product?
This tool is perfect for cat owners battling litter tracking or household pet odor, and for those who want a discreet litter enclosure that complements modern interiors. It’s ideal for multi-pet homes needing a dog proof litter box or for homes with active cats who enjoy privacy.
Consider this model if you have younger or mid-sized cats accustomed to jumping, and if you prioritize easy cleaning and odor reduction. However, cat parents with seniors, large breeds, or mobility-challenged pets may want to look for low entry or side entry alternatives better suited to their needs.

Frequently Asked Questions
- Is the lid strong enough to hold heavy cats?
The grooved cover is designed for stability and supports typical jumping cats. Large cats over 15 lbs may cause slight flexing, but most users report no dents or cracks with regular use. - Does this model reduce pet odor as well as a covered litter box with a filter?
While it does not have a filter, the enclosed design traps most odors and outperforms traditional open boxes in odor containment. - Is assembly required?
Minimal setup—just snap on the lid and attach the included scoop. No tools or complex installation needed. - How does the top entry help with litter tracking?
The top entry system forces cats to exit over the ridged lid, which brushes off excess litter on their paws. That’s how the top entry provides a significant reduction in tracking versus open or standard covered designs. - Will this fit in small spaces?
Its compact footprint works for many apartments or bathrooms, measuring about 20.5″ L x 14.75″ W x 14.5″ H. However, be sure to compare dimensions to your desired location before buying.
