Abstract
The present invention is directed towards a clump recognition animal litter that enables a user to visually identify and dispose of all used litter portions from unused litter, regardless of clump size and clump location within the litter. The clump recognition animal litter comprises a clumping component and a color-indicating material. The litter clumps and displays a color in response to wetness.
