This is by far hands down the best litter!  It keeps the odor down, and it makes it easy to clean the litter box.  I've tried the cheaper kinds and not only is the odor not contained with a cheaper brand, but my cat will go outside of the box unless I have the Tidy Cats in her litter box!

The clumping makes it easy to clean, and I am a clean finatic, so I like fresh smells to and I achieve both with this litter.
