How to Prevent a Dog From Getting to the Cat Litter
Many dogs find cat litter boxes irresistible — much to the chagrin of everyone else in the house. If you’re sharing a home with both a dog and a cat, here are some practical, tested ways to keep the dog out of the box.
Creep Access, for Medium to Large Dogs
For dogs meaningfully bigger than your cat, “creep access” works well: place the litter box in a small room, closet, or ventilated space, and leave the door open just wide enough for the cat’s head to fit through, but too narrow for the dog. A cat door cut into the bottom of a door or wall, sized for the cat only, accomplishes the same thing. A simple chain across the doorway (removable when you need to enter) can work too. The concept borrows from “creep feeding” on farms, where narrow openings let young animals reach food that adult animals are kept out of.
The Special Challenge of Small Dogs
Creep access gets much harder when your dog is close to the cat’s size — a small terrier or a Chihuahua, for example, can be just as motivated (and just as capable of squeezing through) as the cat itself. In these cases, height matters more than width: an opening positioned several inches off the ground, well above where a small dog can comfortably reach or climb, tends to work better than a narrow-but-low opening.
Litter Furniture With Elevated Access
A well-designed litter box enclosure with an elevated jump-access opening — rather than a hole cut into the front, back, or side at floor level — makes a real difference. Cats can jump up and glide through an opening set higher on the enclosure, while most dogs simply aren’t agile enough to follow. Look for litter furniture where the access point sits several inches above floor level with the litter pan itself enclosed below, rather than furniture with a low, easily-reached opening. Good ventilation matters too — an enclosed box without adequate airflow isn’t pleasant for the cat using it.
If you have an older or arthritic cat, keep in mind that elevated or narrow access points can become difficult for them over time — you may need to switch back to a simpler, low-lip pan as your cat ages, even if that means going back to creep-access or supervision strategies for the dog.

Good post! And thanks for the links to the sites (and pretty pictures). I am glad I don’t have dogs and have to deal with this issue, though, as most behaviorists say cats prefer litterboxes that are not enclosed or with ‘hoods’ and all mine are open. I have one couple who have 2 cats from me as well as a dog and they actually installed ‘Invisible Fence’ inside their home and the room that the cats boxes are in is ‘electrified’ so the dog who wears the tag on his collar won’t go in there. Great idea, isn’t it!
Fabulous idea! Thanks for the tip. And it’s true, cats prefer a large,open litter space, but with some privacy from noise and invaders like children.
