Why You’ll Love This Self Cleaning Cat Litter Box

  • One Petree Litter Box can live 3-4 cats. If you have one cat, you’ll clean the waste drawer once a week. If you have two cats, you’ll clean the waste every 3-4 days. If you have 3 cats, you’ll clean every 1-2 days.
  • It will not turn when your cat is inside. Our patented cat protection system will detect your cat presence once your cat is inside the globe.
  • the Petree Litter Box simply requires clumping litter. Some silica gel litter beads and crystals can also be used with the Petree Litter Box, as long as they pass through the screen. Alternative, plant-based litters may also work, but these tend to form looser clumps that can cause condensation in the waste drawer. When using a plant-based litter, we recommend emptying the waste drawer and cleaning more frequently. Litters that do not work in the Petree Litter Box are the strictly absorbent, non-clumping or loose-clumping litters, newspaper-based litters, and absorbent wood pellet litter.
  • Petree Litter Box will not remove all odors. However, the waste is removed and contained the the waste cabin, which will significantly reduce the litter odor in your room. While Petree Litter Box is very effective with the odor control, the overall level of odor also depends on the amount of cats, the type of litter you use, how frequent you change the drawer and your cat’s diet.

1. You need to put litter in the litter box first before you start initiating the machine.
2. Only cats that are 3 month older can use Petree Litter Box.
3. After you clean up the dumpster, you need to reset the machine to restart.
4. Don't put anything on top of the litter box to avoid misguiding the gravity sensor

Why You’ll Love This Self Cleaning Cat Litter Box

  • Malfunctioning: The moving rack is getting disconnected from the base when in cleaning mode.
  • It has been a week but my cat has not used it, not once. He continues to take poos and pees outside, ignoring this new litter box I just bought. It’s been a bother because of the smell reeking from the outside that travels indoors and I still continue to clean up after him every time. I’ve tried using different types of litter because it might be the quality but still no improvement. I tried removing the hood because he might feel stiff inside but still no.
  • I will just say, I am not a happy camper with this litter box. It is not big enough and I guess I should have bought two or three because one is not doing the job. It’s pretty-looking though.
Things to Consider:
  • Cats over 15 pounds might feel confined by the hood
  • It can store up to a week’s waste.

8 Best Self Cleaning Cat Litter Boxes 2021-catgenie

Why You’ll Love This Self Cleaning Cat Litter Box

  • 100% self-cleaning, self-sanitizing, and self-drying—hands free for you
  • Offers some of the highest available reliability among auto cleaning litter boxes
  • Instead of kitty litter, this unit uses dust-free washable granules (washed right in the device!), saving you time and money
  • Materials are high quality, safe, and long-lasting
  • Considered the best litter box for multiple cats

Some Disadvantages & Things to Consider

  • The CatGenie needs a cold water line, drainage, and outlet in order to work, so installation can be a bit of a hassle
  • Users have noted that sometimes the waste drainage system can get clogged up with kitty hair—but consider it one more incentive to maintain a regular grooming routine for your furball (especially if she’s longhaired)
  • It’s normal for there to be a foul odor emanating from the unit during the cleaning cycle (consider installing the unit away from high-traffic areas in your house)
  • It’s one of the more expensive models

The CatGenie is great for people who care about hygiene and who would like as little involvement in their cat’s litter box as possible. If you have a spare bathroom or some other space with cold water access and an outlet, it’ll work great for you. You’ll just need to be aware that clogs in the drainage system can happen, a potential problem that will need attention. Fortunately, you can mitigate this problem by regularly grooming and brushing your kitty.

6. ScoopFree Ultra Self-Cleaning Litter Box (Price: $118.97)

This model uses a highly absorptive crystal litter that dries out solid waste and absorbs urine to avoid leaks. A rake cleans out the disposable tray thanks to an automatic timer (which has 3 settings to choose from), and dumps the waste right into a closed compartment.

8 Best Self Cleaning Cat Litter Boxes 2021-scoopfree

Why You’ll Love This Self Cleaning Cat Litter Box

  • Pledges to offer 5 times better odor and moisture control compared to other kitty litters
  • The concealing hood offers privacy for your furball and decreases the likelihood that she’ll track crystal litter around the house
  • It’s less expensive compared to other automatic systems, but still considered fairly high quality
  • It’s sufficient to cleanly absorb up to 20 days worth of urine, or until the disposable tray needs to be tossed
  • You can even use it to monitor your cat’s digestive health since it keeps track of how many times she uses the box!

Some Disadvantages & Things to Consider

  • While the ScoopFree Ultra Self-Cleaning Box is one of the leaders in odor control, the litter crystals themselves can have a noticeable scent of their own. Avoid this issue with a quick stir of the crystals about once a day, and keeping the box in a well-ventilated area
  • If your kitty scratches a ton, she may end up accidentally scratching the cardboard at the bottom of the disposable tray, which could lead to leaks. It’s rare, but if you’re concerned about it happening, you can opt to put a permanent plastic tray under the crystals—just means you’ll have to be a bit more involved in the cleaning process

So, if you’re willing and able to buy the disposable crystal trays that go with the unit, and are looking for ideal waste odor control, this model could be the right choice for you. Expect to change out the crystal tray about every 10-20 days if you live in a single-kitty home (it may not be feasible if you have many felines).

7. Littermaid LM980 Mega Self-Cleaning Litter Box (Price:$78)

Do you have tons of kitties roaming around your home? The Littermaid LM980 Mega is a great option. As its name implies, it can hold up to 50% more kitty litter compared to other brands.

  • You’ll have to make sure you don’t put too much litter inside since the sensors can get dusty

Not ideal for cats who create a lot of waste and/or animals with urinary issues

Just be prepared to scrape urine clamps from the bottom of the tray, since the rake may miss the smaller clumps.

Why You’ll Love This Self Cleaning Cat Litter Box

  • Comes with a 1-year warranty
  • Thanks to the continual waste removal mechanism, you can get more “use” out of your litter since there’s less of a chance for foul-smelling bacterial growth
  • You can easily expedite the waste removal process by lining the waste bucket with any kind of plastic bag
  • It’s a super quiet motor (impressive given that it runs continuously!)
  • The unit is small and affordable, making it a great choice for pet owners in apartments or other small spaces

Disadvantages & Things to Consider

  • Got a big kitty? She probably won’t fit—this unit is designed for felines weighing 12 pounds or less
  • If your furry friend is particularly finicky, she may not like the movement (despite how slow it is)
  • Occasionally, the device may make a grinding noise—fix by cleaning litter out of the space between the base and the rotational plate
  • If you use cheap litter with this product, waste may clump under the sifting device

While compact and hygienic, this device does need a bit of daily love and maintenance. Otherwise, it may be a great option for you and your small and healthy kitty.

  • On occasion, clean litter may fall into the disposable waste tray, which is a bit wasteful from a financial aspect
  • Litter tracking is not unusual with this roly-poly design, but a mat beneath the unit should help reduce this problem significantly
