Hello again, Skye Blake here, discovering what your cat wants you to know about sifting litter boxes.

While they’re a type of “self cleaning” box, they’re different from rotating ones (like Litter Robot™).

What’s a Sifting Litter Box?

Sifting boxes do exactly what their name implies… they sift like a colander to separate pee clumps and poop lumps so you can easily scoop or dump the soiled parts and reuse the good litter.

This is done either automatically or manually.

Automatic sifting boxes have rakes that push soiled litter out while keeping unused litter in the box.

You then open the tray and dump what’s in it.

Manual sifters are sieves that you shake to allow unused litter to fall to the bottom.

The clumps and waste left on top are thrown away.

Sifter boxes come either open or covered and often use only certain types of clumping litter, usually clay or silica.

Some sifter boxes are large, so check the dimensions to be sure it’ll fit where you want it.

Automatic ones have to be near an electrical outlet.

Some also have weight sensors underneath to sense when your cat gets in and out of the box.

This means the box should either be on a hard floor or mat (if on carpet).

Some sifting boxes come as both manual and automatic, so you have both options when you want them.

Some require liners, waste receptacles, carbon filters and/or other accessories, as well as litter.

Keep this expense in mind when deciding if these boxes are financially workable for you.

There’s quite a bit of variety in sifting automatic litter boxes. They range in shape from rectangular to round and egg shaped.

Everything from low-sided to high-sided, open or covered boxes are available at pet stores and online suppliers like Amazon and Chewy.

Some are only available at the manufacturer’s website, such as ChillX AutoEgg Self-Cleaning Litter Box (offers new and reconditioned units).

If your cat is a mad litter flinger or stand-to-pee character you may prefer a box that comes with detachable sides and/or cover.

Manual sifting boxes are available in a few different styles.

Some use levers that you pull to scoop waste and others are basic with sections to lift and sift.

The Boxscoop is an example of a lever-style manual sifting box.

If you’re having problems with a cat peeing or pooping outside the litter box, take a look at “Behavior” to find out what might be causing this and how to fix it.


Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
