Automatic Litterbox Central

The litter in my Litterfree unit doesn't seem to dry very well. The dryer does blow hot air, and for a [u]long[u]time.

Does anyone else have this problem, and any suggestions to remedy this?

It looks like the new Cat Genie actually stirs the litter while drying. I bought my Litterfree "used". I don't suppose it ever had any means of stirring it's litter.

Comments / Suggestions Appreciated!!!
