The 7 Best Dog-Proof Cat Litter Boxes of 2021

Families with both cats and dogs have unique challenges.

If, like us, you are both a cat and dog person, you’ve no doubt noticed your pup’s problematic fascination with the kitty litter box. There are products on the market that gate or lock the door for dogs (though not the smallest pups) while allowing cats through, and letting people through after opening the gate. Those gates can be tricky to open, but they serve a purpose if your set-up is appropriate.  But if the litter box room doubles as a bathroom, as most do, there also is the necessity of closing the actual door, which can be awkward with a gate in place. That set-up will work for some families, but not for all. Fortunately for the rest of us, there are cat litter boxes that are dog–proof!

Dog-proof cat litter boxes come in three basic configurations and styles:

  1. Top/High Entry: These litter boxes have entry holes high in the the walled litter box, making it all but impossible for a pup to reach all the way in. For more on top entry litter boxes, see our article here.
  2. Turnabout Entry: These litter boxes are dog-proof because they turn a corner before reaching the litter.
  3. Distant Entry: These litter boxes have a space between the entrance and the litter box, making it too far to reach for even the most persistent pup.

Most of these configurations have the added bonus of creating a space for your cat to walk over and drop any tracked litter before reaching your floor. They also tend to have a more pleasing appearance than traditional litter boxes. Some even double as furniture or storage.

Things to consider when choosing a dog-proof cat litter box:

  • Are the width and height of the space available large enough to fit your chosen dog-proof litter box?
  • Does the litter box enclosure serve as a litter box itself, or does it serve as an enclosure for the actual litter pan?
  • If it serves as an enclosure, is it big enough to hold your chosen litter box?
  • Is the litter box easily accessible for cleaning?
  • If it serves as the litter box itself, does it require special bags? Are they included or easily acquired?
  • If no bags are involved, is the litter pan easily accessed, removed, and cleaned?
  • Are the entry and interior spaces large enough to accommodate your cat?
