Funny, this whole site is dedicated to reviews of different litters, arm and hammer, special kitty etc...
Sadly many of you may not know that most all of these brands are packaged by 1 facility. I used to work there. We made special kitty, arm and hammer, petco, albertsons brand, k mart brand and many others.
The main difference might be a scent change. Baking soda is just baking soda regardless of the brand of litter. We would load the line up with 1 brand then go right into another.
Many of the brands use the same formulations. One of the many ripoffs we fall for. haha. Different brand names cost more. But clay litter is basically all the same.
