This stuff is AMAZING! My mother recommended this to me, after she told me that she once forgot to clean the cat box for a month (eew, lol) because there was never any smell. Now, I have three indoor cats, while she has one outdoor/indoor cat, so where she went an entire month without stink, I could not do the same (nor would I bother to try). BUT I did manage to get a couple extra days out of my litter, thanks to the odor protection this has. I went from changing the box every other day to every three days. It's a nice break, it smells much better than clay litter, and it's good to my wallet, as its affordable. Thank you, A&H!
