I am so impressed with Cat Spot litter! I purchased the compostable litter to test drive it with my 11 yo cat. I put the box next to his existing, and cleaned out, refilled with crystals litter box. He sniffed Cat Spot, went to his, came back, sniffed Cat Spot again, then pranced right in. I then purchased the clumping version and thought it, too, was compostable, then realized it’s not. I’ll use this up then return to the compostable version. It’s light, fluffy, mixes well and no odor. Only issue is my cat kicks so much of it out of the box because it’s so light!
