ABSTRACT:
A self-cleaning kitty litter box and method for cleaning the litter box are disclosed. The kitty litter box has a removable pan in which kitty litter is placed. A motor and timing device are provided for periodically moving a rake through the kitty litter so to push solid waste to one end of the pan. The rake is then rotated in contact with a stop out of the pan, the rake then moves forward and drops the collected solid waste into a storage tray. The motor and timer allow this process to be periodically repeated without involvement of the cat owner until ultimate disposal of the cat waste is desired.
