I don't like litter that scoops. I buy Fresh Step, but you can get "plain" litter and a box of store brand baking soda to add to the litter pans.
The way the cat rescues tell people who adopt kitties is to try to give each cat its own litter box.
I've been told that WM has cheap litter. I buy mine at either Food Lion or at Harris Teeter.
Adding baking soda helps with odors.
If I had lots of cats, I probably would use cheaper litter, but I have just one very spoiled little cat. She has a litter box on both floors of the house.
