We just recently got our 2 new kitties to total 4. We've had them 3 days now and the house has started to smell TERRIBLE like cat poo. We have only 2 boxes that are in the cat room but will be adding a 3rd. We are using Arm & Hammer litter from Wal Mart but I am thinking about changing that also. Has anybody had any good experiences with litter that keeps the smell down to a minimum? I know I will have to start scooping a lot more, probably atleast twice a day. I just want to do everything I can to keep our house smelling good since we've promised ourselves that we wouldn't have a house that smells like cats. Please give me your suggestions on litter that works for you or anything else that might work. Thanks!
