I was using Feline Pine, which I liked. But then I got a coupon for World's Best Cat Litter and I like it better. Chester Cheetah has furry toes so he can get litter stuck in there easily, especially the clumping clay litter. I have found he tracks it less with the other kind.
I hope you...
strange_wings is correct. Most vets will sell it by the vial if you want to save right then, in the long run though it is always cheaper to buy by the package.
