Query: Finally, an odor free apartment!!

Living in an apartment, it's hard to keep it smelling clean when there's a cat around. I was using Arm & Hammer for a few months until I realized it wasn't doing a damn thing about odor. I bought the clumping, multiple cats Arm & Hammer litter but even after my cat would use the litter box once, it would imminently stink up the place! Finally I decided to buy a new brand and this one works amazing! I live in a one bedroom apartment and you could imagine how hard it is to keep it odor free, I've had this litter for two days and already I notice a BIG difference. I come back from school/work after a few hours of not cleaning the box and the apartment smells fine, no nasty kitty poop and pee smell! This is a big sigh of relief. And the stuff clumps up pretty well, almost leaves no residue behind. Will definitely continue buying this product.
