Did Nothing For Me - Total Waste of Money
I put two bags of these rocks in a very small closet that holds my shoes and a litter box.  The litter box is cleaned well and regularly - the shoes have all be cleaned and deodorized to the best of my ability - there's still a smell in there.  I left those two bags in there for weeks and nothing changed with the smell.  In fact, a cat that doesn't even use that litter box went in there and specifically urinated on these rocks.  That cat actually has a more intense pee smell than the one that uses that litterbox, so now my closet is 10x more worse off than it was before and I have to go through the intense arduous process of trying to get the smell out.  Aside from the fact that cat was weirdly attracted to the rocks, the issue boils down to the rocks not working in the first place.  It's shame from start to finish - I really wanted these to work.
