No cat litter box is guaranteed to stop every dog from reaching used litter. Top-entry, hooded, high-sided, and automatic designs each make access harder in different ways; the right choice depends on your dog’s size and persistence, your cat’s mobility and body size, and how much space you have. Catster’s 2026 guide names ten options, but its picks are editorial selections—not a universal or independently verified ranking. Read Catster’s guide.
How to choose a litter box that keeps your dog out
Start with your cat, not the dog. A box that your cat avoids or cannot enter comfortably will not solve the problem. As Catster’s Rachael Gerkensmeyer puts it, “As important as it is to keep the dog out of the litter, your cat’s comfort and safety take priority.”

- Match the entry to your cat’s ability. Top-entry designs can be unsuitable for cats with mobility limitations or those that struggle to jump. Consider the cat’s age, size, and comfort using the opening.
- Consider the dog’s reach. High sides may hinder a small dog but are less likely to deter a large dog that can reach over. A cover or top opening may add another obstacle, but persistence and setup matter.
- Check usable space, not just exterior dimensions. A box can look large from the outside and still feel cramped inside. Some top-entry models are a poor fit for larger cats.
- Think about your cleaning routine. Top openings, lids, liners, and automatic waste systems change how you scoop, empty, or maintain the box. An access barrier that is frustrating to clean may not work well for your household.
The designs are not interchangeable: top entry limits the route in, a hood or door partially encloses the pan, high sides create a barrier around an open pan, and automatic systems move waste into storage. None is proof against every dog.

| Pick | Access or waste design | What to weigh before choosing |
|---|---|---|
| Catit Jumbo Hooded Cat Pan | Catster’s overall pick. Hooded pan with a removable transparent door, carbon filters, and liner anchors. | The covered entry may be easier for some cats than jumping into a top-entry box. Catster notes that the latches can be tricky. A hood and door deter access but do not guarantee exclusion. |
| IRIS Large Round Top Entry Cat Litter Box & Scoop | Catster’s value pick. Top entry, paw-litter holes in the lid, and a scoop included. | Catster describes it as small and notes scooping difficulty. Check that the cat fits comfortably and that the round shape suits your cleaning routine. |
| Whisker Litter-Robot 4 | Automatic cleaning with waste storage, as described by Catster and Cats.com. | Cats.com says the cycle can be set as low as three minutes and notes the high price. Automatic cleaning is not the same as physically blocking a dog; cat fit, reliability, and cost matter. |
| Petmate Top Entry Litter Box | Top entry, tall walls, and a textured lid intended to catch litter. The manufacturer says its design keeps dogs from reaching the litter. | Check the cat’s ability to use a top opening and compare its size with the listed exterior dimensions: 20.290 × 15.070 × 15.200 inches. These are manufacturer-published measurements, not interior dimensions. |
| Clevercat Top-Entry | Named among Catster’s ten picks. | The cited source information does not establish detailed specifications or a distinct performance result for this model. Check the current product configuration and entry dimensions before choosing. |
| Kitangle Slope Style | Named among Catster’s ten picks. | The cited source information does not establish detailed specifications or a distinct performance result for this model. Confirm the current design and whether your cat can use its entry comfortably. |
| Frisco Top Entry Cat Litter Box Large | Cats.com describes a flip-top lid and top-entry access, and says it may suit small- to medium-sized dogs. | Cats.com warns that larger cats may find it cramped. Compare the cat’s size with the usable interior and opening. |
| Nature’s Miracle High-Sided Corner | Named among Catster’s ten picks as a high-sided corner-style option. | High sides can create a hurdle for some dogs, but an open pan is less likely to stop a large dog that can reach over. Check the entry height for your cat. |
| Tidy Cats Breeze Hooded System | Named among Catster’s ten picks as a hooded system. | The cited source information does not establish detailed specifications or a distinct performance result for this model. Verify the current system configuration and ongoing supply requirements. |
| Frisco High-Sided Cat Litter Box Extra-Large | Cats.com describes 10-inch sides and a low entry; the open, high-sided design may deter small or medium dogs. | A larger dog may reach over the sides. The low entry may be more accessible for cats that cannot manage a top opening. |
When top entry is the better fit
A top-entry box makes the dog approach from above, rather than through a low front opening. That can add a meaningful obstacle in some homes, but it only works if the cat can comfortably jump in and out and has enough room once inside. Catster cautions that top entry may not suit cats with mobility limitations.
Petmate describes its Top Entry Litter Box as having taller walls and a top-entry opening that keep dogs from reaching the bottom. That is the manufacturer’s product claim, not independent proof that every dog will be deterred. The official listing gives exterior dimensions of 20.290 × 15.070 × 15.200 inches and says the product is made in the USA from 95% pre-consumer recycled materials; both are manufacturer-published product information. See the Petmate Top Entry Litter Box listing.

When a hood, high sides, or automatic cleaning makes more sense
Hooded boxes
A hood or door partially restricts access without requiring the cat to climb in from above. This may be worth considering when a cat will not use top entry, but a dog may still get through or push past a door. Catster notes that the Catit Jumbo Hooded Cat Pan has a removable transparent door, carbon filters, and liner anchors, while its latches can be tricky.
High-sided open pans
High sides can make it harder for a small or medium dog to step into a pan, while leaving a low entry for the cat. Their limitation is reach: an open box is less likely to deter a large dog that can put its head over the side. Cats.com describes the Frisco High-Sided Extra-Large as having 10-inch sides and a low entry.

Automatic waste handling
Automatic boxes address the problem differently by moving waste into a storage compartment. Cats.com describes the PetSafe ScoopFree with Top-Entry as using an automatic rake to move waste into a covered compartment. That approach does not necessarily prevent a dog from reaching the box itself. Verify the current configuration and required consumables before buying.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What to do if your dog still gets into the litter
If changing the box does not stop access, change access to the room or area as well. Catster suggests a cat-only room or an elevated location, provided the cat can reach it safely. Catster also advises discussing training with a veterinarian. The useful target is a setup your cat can reliably use and your dog cannot casually reach—not an absolute guarantee from a product label.
