Great at first but it tracks ALL over the house.
I was already happily using the Tigerrino crystal Non-clump litter, the only thing I didnt like is the yellow crystals which look awful although they don't smell. I tried the Tigerino Crystals fresh so that I could take out the clumps, you need an really deep litter tray, 16 cm plus and you need to keep the litter thick enough so that the lumps form before it reaches the base, if your cat is a digger then it won't work and you are left with a granite slab, very hard to move, Smells nice though!
