What’s the Best Cat Litter for Automatic Litter Boxes?

After you’ve chosen an automatic litter box, your next decision should be which type of litter to use with it. Cats are finicky about their litter, so this is a pretty important choice to make. And this stuff isn’t cheap, so you definitely want the best cat litter for the money.

Automatic litter boxes require either premium clumping litter, proprietary litter trays, or special litter crystals to work. Before looking at litters, read the instructions for your box and find out which kind of litter works best. You don’t want to waste money on a pricey clumping litter if your box only works with flushable pellets.
