Buying Guide for Automatic Litter Boxes

Owning a pet, particularly a cat, can be a great experience. These tiny animals are soft and cuddly. There’s never a dull day in your life if you have such a pet around.

But even with that said, there’s something about being a pet parent that sucks. And that is having to scoop and clear the cat litter box from time to time.

Not only is it tiring but it’s also repetitive. And if you feel puking at the sight of poop, you’ll also find this task quite gross.

Fortunately, modern technology has enabled the world to make some nifty advancements on this front. And indeed, the entry of the best self-cleaning litter boxes promises to make life a tad better for all of us. When it comes to choosing one of these robots, these are the factors you should pay attention to.


Indeed, size does matter as far as litter boxes, in general, are concerned. We generally recommend picking something that provides your pet with just enough space to go about their business.

A simple rule worth keeping in mind is that the car should fit inside the litter box comfortably, always. There should always be some room to spare.

Also, the litter box should be spacious in such a manner that the cat can avoid any poop they might have deposited in earlier visits.

So, make sure that the box you settle for is as tall as your cat is. If possible, take the measurements of your cat from their nose to the tail extended. Use those dimensions to pick the ideal length of the litter box.

Overall Design of the Litter Box

At this point, the battle is typically between the covered and uncovered litter boxes. Unfortunately, there’s no definitive answer on what to choose. You need to carefully study your pet’s behavior before you make a choice for them.

Generally, covered litter boxes are loved by cats which value privacy as they do their thing. It, however, might look a bit scary for cats with trust issues. Also, if your cat has asthma or arthritis, you’re better off getting them an uncovered litter box.

The Self-Cleaning Frequency

The ideal cleaning interval is as often as your cat likes to poop. But generally, anything that allows you to make adjustments of as few as every 20 minutes should be good enough. That said, it’s always best to go for a box that enables you to create customized settings.
