Your domestic cat (Felis catus) has a strong, direct lineage to the African wildcat (Felis lybica) and thus, shares similar preferences to its ancestor. They basically live in Saudi Arabia, where it is very sandy. This is thought to be the reason they prefer a sand texture for litter. I have not found a cat yet who prefers the pellet litters. I have been using sWheat Scoop litter because of it’s natural odor controlling wheat enzymes – they really seem to be working well to control odor. It also clumps naturally, creating solid, easily removable clumps that don’t stick to feet and track all over the house. Whatever brand you choose, pay attention to the texture and think Arabian sand!
