I haven't had a problem with the Pearls being all over the house. Some of them do gather around the litter box after awhile, but I just sweep them up every so often.

I think I lucked out because my cat is a neat freak. Although she does love to dig a lot in her litter box, she manages to keep most of it in there. I buy the Low Tracking kind so the crystals are bigger and never get stuck on her.
