The best cat litter , no hurting to their feet !
My 2 cats have been on Nullodor litter for over 5 years.It is the only kind of Silica litter in the smooth round form I can find ( not sharp crystals) which is easy on cat's feet. Cats do bring litters out of the litter box doesn't matter what kind of litter .simply just put a cat mat to trap the litter in front of the box . For 2 cats sharing one closed box with a swing door: change about 1 time / week . no smells . Nulldor now has a new colored one ( more expensive ) and not as good as this
