This type of litter is typically made from bentonite clay, which is a type of clay that is highly absorbent and  it forms solid clumps when your cat urinates. Clumping clay makes litterbox scooping and cleaning easy. Drawbacks are that this type of litter is dusty, non-biodegradable, and heavy to cart around.
