A while back someone posted a question asking for information on a
self-cleaning litter box. At the time I replied I didn't have the name
or number of the system, but found it today if anyone needs it.
It is called the LitterMaid System & retails for $199 according to the
ad (plus $16 for s&h). Their number is 1-800-992-2966
