Maintaining a clean litter box is an important part of sharing your home with a cat. Cats are naturally clean animals and are about as fond of clumps of poop and pee as you are. No, really. Leave it too long, and many will find other spots in your home to take care of their business. Before that happens, let’s take a look at some mechanized and automatic cat litter boxes that improve life for you and your cat.

Everyone Loves a Clean Litter Box

Rover’s cat behavior expert Mikel Delgado recommends scooping every litter box in your home one to two times a day and doing a full litter change every two to four weeks (if you use an unscented clumping litter). Of course, daily scooping can be a real pain if you work long or irregular hours, have a busy schedule, or clean up after multiple cats. What to do then? Many cat owners have turned to automatic and mechanical litter boxes for help.

If you’re thinking about converting to an automatic litter box, there are a few things to keep in mind. Although automatic litter boxes make maintenance easier, they still require your attention and should be checked and cleaned regularly. Also, the fully automated ones are not safe for kittens. PetMD recommends using those only for cats 6 months or older.

When checking out automatic and mechanical litter boxes, keep in mind that most automatic litter boxes need to be plugged directly into a nearby three-prong outlet—they draw a lot of power, and should not be used with power strips. One of the automatic litter boxes on our list also needs to be near a cold water pipe and a toilet or waste drain.

One last thing: consider your cat’s personality when considering fully automatic cat litter boxes. If your cat is spooked by loud noises or moving parts, select a model that delays its automatic cleaning until several minutes after your cat has left the box. Or choose one of the semi-automatic, mechanized litter boxes that you operate yourself.

Checking Out Automatic and Mechanized Cat Litter Boxes

Ready to remove one more thing from your daily task list? We’ve rounded up the best automatic cat litter box options below. We start with the fully automated boxes and get into the human-powered mechanized boxes in the second half of the list.

Automatic No-Scoop Litter Boxes

The improved version of this self-cleaning litter box is the key component of an entire litter system that includes special litter and options for a front- or top-entry cover. Its sensors detect when your cat has done their business and 20 minutes later proceeds to rake away the mess. The ScoopFree crystal litter (sold in packs of three) includes disposable litter trays for quick clean-up. The cover options, and the reputation for durability, make the mid-price, second-generation ScoopFree a top pick.

  • Choose from a top-entry, front-entry, or topless box to match your cat’s preferences
  • Use with ScoopFree’s own crystal litter (lavender, original, or sensitive)—it’s lightweight and doesn’t track outside the litter box
  • A health counter (included) monitors how often your pet uses the box so you can see any changes in litter box habits

This flushable litter box is quite pricey, but ideal for people who don’t want to deal with heavy, messy, expensive cat litter ever again. The initial set-up involves connecting the CatGenie to the cold water line in your bathroom or laundry and then connecting its waste tube to a nearby drain. Like all automatic litter boxes, it also needs to be plugged into a power outlet. The good news is that in most cases, all this can be done by a homeowner—no plumber needed.

Once the CatGenie is in place, your cat is ready to use the washable granules that will feel like familiar litter. After your cat has used the granules, the CatGenie rinses them with water and a cat-safe sanitizing solution. Liquids and solids rinsed from the granules are flushed to the nearby drain. (You will have to flush the toilet.) Finally, the reusable granules are heated and dried—and ready for your cat’s next visit. Your only maintenance cost will be replacing the sanitizer cartridges.

  • Ideal for one to two (but no more than three) average-sized cats that are at least 6 months old
  • Washes and dries reusable litter granules
  • Uses water and a cat-safe sanitizer solution (on cartridge included) to flush waste and wash granules
  • Features include an app that monitors use of the box

More Tips on Automatic Litter Boxes

Your cat may need somement to try out an automatic or mechanized litter box. Experts recommend keeping the old box available but placing the new box next to it. Let the old litter box get a little dirty so your cat will seek out the clean litter in the new box. At first, keep the automatic functions of the new litter box turned off. Once your cat is using the new litter box regularly, turn on the automatic cleaning cycle and enjoy a life of significantly less scooping.
