How To Pick A Self Washing Cat Litter Box

There’s something about new technologies that sometimes make us worried if they’re worth the money spent and if they’re safe. self-washing litter boxes can be a great asset but still, there’s so much where something could go wrong because they differ largely in build, functionality, the way they dispose of litter and more so choosing the best one might not always be an easy task.

Motion Sensor Activation – Since they’re automatic, they should have a motion sensor to start the cycle of cleaning. It’s good to have one because if you’re busy, you can’t always be there to turn it on when you’re cat is done using it. The cleaning cycles prevent odors from spreading so if they don’t have a sensor, maybe you’re better off with a different one

Tall Wall Build – Because most of the time, you’re not cleaning out the litter box, there might come a time where there’s mess around the litter box. Tall walls or enclosed litter boxes prevent that so if you’re looking to clean even less, opt for a tall wall litter box. But, owning a robot vacuum for cat litter is also a good solution.

Additional Costs – With most of these, you’ll have additional cost every once in a while, depending on which type of litter box you choose. These may include litter, litter containers, filters for odor control, and even trays. With some, you can’t avoid most of these extra costs but with others, you just may.

Litter Quality – All of these work well, but the key to a good litter box is not only the box but the litter as well. You should be looking for ones that have high absorbing power, are dust-free and that may last you a long time. Litter boxes are designed to keep odors to a minimum, but it will work best if you have good litter

To Sum Up

With self washing cat litter boxes, a lot can go wrong. The promised odor control that you get with these can depend on a lot of things and of course, there are additional costs that you’ll have if you decide to go automatic so the one that we’d recommend is definitely the PetSafe Ultra Automatic Litter Box. You can easily avoid more than just one additional cost by getting a reusable tray for litter and the quality of the litter that you would use with this box is of great quality and is long-lasting.
