This crystal litter controls odor better than any other litter I’ve used. I don’t have the automatic system, I just use a regular litter box. I have one 8lb cat and I can go a month with only scooping solids before I have to completely change the litter! It does track some but mainly because my cat gets the litter box zoomies and goes flying out of her box when she’s done using it. Overall I’m very happy with it!
