Did you know dog-proof litter boxes are a thing? Having both a dog and a cat comes with a set of challenges. Your cats would love their own dog-proof litter boxes, for starters. It’s important to give your cat their own territory because they are prey animals and, therefore, can become skittish if uncomfortable, says Dr. Kwane Stewart, a veterinarian based in Southern California. “Giving them their own sanctuary can make a big difference,” he explains. 

According to a Simmons National Consumer Study, 53 percent of households own a pet. Of those, 77 million have dogs and 54 million have cats. And a fraction of those households own both types of pets. [1

Your cat’s litter box should be a sanctuary, where your cat can do her business in peace. But when dogs invite themselves to your cat’s special box, this can be a recipe for disaster. Not only will it make your cat very uncomfortable, but it can also cause unnecessary tension between your pets. 

The solution: dog-proof litter boxes that only the cat in your household can enjoy. While no litter box is 100 percent dog-proof, there are plenty of options out there that can help keep your canine from eating cat poop and messing with your feline’s safe space.

Sizes and Dimensions (LxWxH)27 x 22 x 29.5 inches
ColorsBlack, White

Unlike litter boxes that rely on barriers or small openings to keep dogs at bay, the innovative (and recently upgraded!) Litter-Robot 4 works smarter, not harder, to remove litter box temptations entirely. This automatic self-cleaning litter box is the latest, greatest evolution of the original Litter-Robot, invented over two decades ago by engineer and cat dad, Brad Baxter.

You’ll still find all the core features that made the original so popular, like Litter-Robot’s patented sifting system, which automatically separates your cat’s waste from the clean litter and hides it from your dog’s prying eyes (and nose). But you’ll also discover plenty of smart improvements, like laser and weight sensor technology that keeps your cat safe and also gives you real-time assurance that waste is whisked away before your dog even knows it was there.

Other new features include a WhisperQuiet cleaning cycle, an enlarged waste drawer, and an optional system to neutralize litter box odors. The new-and-improved Litter-Robot 4 starts shipping in July 2022, but you can pre-purchase your unit now and rest easier knowing the ultimate dog-proof litterbox solution is on its way.


  • Patented litter-sifting technology designed to remove waste without clogging or jamming
  • Advanced sensors detect and deposit solid waste in an odor-neutralizing, dog-proof compartment, for effortless cleanup
  • New WhisperQuiet self-cleaning cycle won’t startle your cat
  • Larger 15.75″ diameter opening accommodates cats of all sizes, while enclosed globe provides plenty of privacy
  • Multi-cat design suitable for up to 4 cats
  • Works with Whisker app to track usage, waste-drawer capacity, and litter levels
  • Easy-read control panel for up-to-the minute status updates
  • Included fence helps minimize litter tracking
  • Works well with almost any clumping or scoopable litter
  • 90-day in-home trial
  • Free shipping (except Alaska, Hawaii, and Puerto Rico) 

Things to Consider: 

  • At nearly $650, it’s a big investment…but comparable to other high-tech, app-enabled litter boxes
  • Optional add-ons include a litter trap mat ($40) designed to fit the Litter-Robot’s base, and an OdorTrap system ($15 for 2-pack), which uses plant-based oils to help neutralize litter box odors
  • The Litter-Robot 4 ramp will not be available until late 2022; the Litter-Robot 3 ramp is not compatible with Litter-Robot 4
  • 1-year warranty included but you can upgrade to 3 years for a fee
  • Litter-Robot 4 begins shipping July 2022
  • Some cats may need time to get comfortable using a self-cleaning litterbox

If you don’t want a bulky litter box but still want to keep your dogs from eating your cat’s waste, one that automatically cleans it up is your best bet.

Plus, the unique Rock n’ Clean design makes scoop-free clean-up a breeze, so lingering smells don’t attract your dog.

How to Keep Dogs Out of the Litter Box

The right dog-proof litter box may be all you need to keep your dog out of your cat’s business. But if your dog is especially determined or nimble, you may want to take additional precautions to ensure your cat’s privacy.

If your litter box is in a room with a doorway, Stewart suggests a fence or barrier to keep the dog out. Consider blocking the entrance with a gate that you know your cat can either slip through or jump over, but that your dog can’t maneuver around.

You can also keep your dog active and busy, or train him or her to leave the litter box alone. Cleaning the litter box as soon as your cat uses it is also another option, he says.

Why Do Dogs Eat Cat Litter and Cat Poop?

“Dogs don’t go into the litter box for the litter, they’re after the stool,” says Stewart. “Cats eat a diet higher in protein and therefore their feces has a different taste that many dogs find appetizing.”

Your cat’s poop kind of smells like cat food. Dogs find cat food appetizing and may mistake cat poop for what your feline just ate. That’s all. The downside? Cat poop may be laced with harmful bacteria and parasites that will then find a host in your dog’s tummy. 

Besides the taste factor, some dogs will also go after kitty poop due to boredom or nutritional deficiencies, Stewart adds. “Your vet can advise if it may be a vitamin or mineral deficiency and recommend a diet higher in fiber, fat, or protein,” he explains. “And some dogs simply go stir crazy in the house and look for something to spice up their day. In this case, more exercise or a distraction is the prescription.”

What to Look for in Dog-Proof Litter Boxes

Whatever the reason behind your dog’s litter obsession, a dog-proof litterbox could be the key to combatting their unwanted behavior. And you can find a growing number of options to choose from at pet stores and online retailers.

Designs vary by manufacturer, so be sure to look for features that meet the needs of you and your pets. A dog-proof litter box should be easily accessible to your cat and easy for you to clean, but still deter dogs from snooping around. 

Some effect features include:

  • Litter boxes that have a door.
  • Litter boxes that have a cover.
  • Litter boxes where cats enter at the top.
  • High-walled litter boxes with a small opening.
  • Litter boxes shaped like a dome. 
  • Self-cleaning litter boxes that get rid of cat poop as soon as your cat does the deed. 

How We Ranked Our Top Dog-Proof Litter Boxes

We rounded up the best dog-proof litter boxes for dog-and-cat households by factoring in the different design elements you may be looking for to keep the dogs out: doors, covers, size of openings. We also looked at innovation. Does the litter box clean the cat poop as soon as your cat uses it so the dog won’t have the opportunity to scavenge?

Within those different factors and needs, we narrowed down the list by looking at overall ratings, plus the number of reviews. In other words, we considered litter boxes or brands with 4-star ratings or higher and those with hundreds (or more!) of positive reviews. 

In addition to looking at the pros according to customers, we also considered the cons. Not every litter box is perfect, but depending on your needs, we give you all you need to know to make a good purchase below.
