Faster & Harder (clumping cat litter, that is)

Mrs. Maidenname-455 and I are the proud new owners of a Litter Maid Mega automatic cat box. We’ve got two small furry children - a 16-pound male and a 9-pound female. Both are fixed mutts.

We’re currently using Arm & Hammer unscented, mainly because, unlike other “unscented” litters, it does actually appear to be unscented. Girl kitty has allergy issues, and besides, they both seem to prefer the box when the dirt smells like actual dirt.

However, the A&H takes awhile to set. It wasn’t really a problem when I was scooping the box myself, but the Litter Maid doesn’t really like it. The rake either breaks the large chunks in to smaller chunks that are too small to get picked up, or it impales them on the end of the tines, preventing them from being dumped into the box.

Can anybody recommend a litter specifically for the Litter Maid? We’d really prefer unscented; I’d rather cope with scooping the box every day than force them to use a litter they don’t like. Maybe it’s the humidity in our apartment or something, I dunno.

Any thoughts?

Thanks.
