I got the ScoopFree Premium Blue Crystal Litter Tray 3 Pack and I think it's great! My cat likes it, at first he thought it was to lay in! Now he likes using the litter! It doesn't make a mess at all, it's easy to use with no problem! The litter last a long time with no smells! The litter pan is very easy to discard and change! I love this product!
