First, to clarify, Garfield cat litter has two “sizes” of grains, the tiny and the small. This is the small. When they are out of the tiny (“Garfield Cat Litter Ultimate Clump Multi-Cat, All Natural, Fast Clumping, Perfect for Multi-Cat Homes, Tiny Grains, 10 lb “), I have NO problem substituting the small (this), as this grain is also soft (easy on their toes), and the same exact composition.
