Replacement litter storage is positioned above the box. A mechanism releases predetermined amounts of litter into the box during cycling of a rake that cleans the box. A collection member has a first position where it receives waste collected by the rake. The collection member is disposed between the storage member and the box and at a second position transfers the waste to the storage member. A drive mechanism is mounted to the collection member moves it between the first position and the second position. The combined members in conjunction with the self cleaning litter box provide a litter box that needs no maintenance over long periods.

  • Patent number: 5048465
    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.
