I don't have a tracker mat because the litter box is in a corner of my bedroom, which is carpeted. I put a cotton throw rug between the carpet and the litter box to catch what my cat tracks and kicks. I found a whisk broom and dustpan combo at the dollar store, which I use to sweep up the litter from the throw rug when I scoop the box. That way less litter ends up in the vacuum cleaner. I switched my cat from clumping back to clay litter, because she doesn't track the clay nearly as much. I was thinking to give a try to Feline Pine or Yesterday's News, though.
