I have 3 cats. Right now I am in the process of testing different litters do to the amount of cat poop, smell, tracking, dust and cost. Right now I am down to Tidy Cat with Glade and Arm and Hammer Clump and Seal. Both products cover the smell, clump well. With 3 cats you have tracking. I have 2 litter boxes, needless to say I USE A LOT OF LITTER and CLEAN BOXES DAILY. I like that your product Tidy cat comes in the large size tubs, Arm and Hammer does not come in Large amounts. I like your tubs because I use them for storing their food after rinsing out. One of my cats has a digestive problem so her poop really smells to high heaven and your product does cover the smell very well Clump and Seal also covers the smell. Just wanting to say thank You for your product especially the 35# tubs. I am a senior citizen so when your product goes on sale I usually buy 2 before the sale goes off. Thanks again.
