As catnapper posted, be very wary of the crystal litter, especially for such a young cat. If she is playing with it, she may try eating it and that stuff is not good for anyone's insides.

I've been using SWheatScoop for about 6 months now and I do like it. I've found it's only a problem to scoop when the wet litter is still very wet - then it falls apart. I use a stainless steel scooper and cut across the clump from the bottom of the pan which takes it all out cleanly. One of my cats pees considerable amounts because he's getting extra fluids but I still find it's easy enough to scoop. Anothe cat likes to pee in the corner of a box and for that I tip the box to slide the litter away and use a paper towel to scoop the clump out. When I want to be really fast in the morning, I simply pour the clean litter out of one pan into a clean one, leaving the clumps behind to be cleaned up when I get home. Another good thing about SWheatScoop is that it makes the litter boxes much lighter to lift and move around than any clay based litter.

You do use more litter than you would with a clay clumping kind, so it is more expensive for that reason. I prefer it because it has the smallest amount of litter dust I've ever seen - in fact, you can barely see any. Also, the litter does mask urine odors without any perfumes. I think it is healthier for both me and my cats. I have 7 cats and they all like it well enough to use it.
