7. The automated cat litter box of claim 2 , wherein said litter pan comprises a guiding rim that extends outwards from the interior sidewall of said pan.

8. The automated cat litter box of claim 7 , wherein said lip and said guiding rim guide said cleaning carriage during an automated cleaning.

9. The automated cat litter box of claim 2 , wherein said rotatable grate comprises vertical or curved tines connected to a pivot rod.

10. The automated cat litter box of claim 2 , wherein said pan shallows and curves at the end opposite where said carriage rests.

11. The automated cat litter box of claim 10 further comprising a ramp having horizontal ridges at said shallow end.

12. The automated cat litter box of claim 2 , wherein said driving mechanism is contained in a cabin positioned on the outside of said pan, but attached to and adjacent to said waste drawer.

13. The automated cat litter box of claim 12 , wherein a push lock release positioned on a top lid of said cabin provides access to a motor and mechanical elements used to drive said cleaning carriage.

14. The automated cat litter box of claim 13 , wherein said pins extend downwards from said frame traveling said length of said pan to elevate said cover so that said cleaning carriage can travel said lip during said automated cleaning.

15. The automated cat litter box of claim 14 , wherein a ventilation or a filter hole positioned on the top of said cover provides fresh air to the internal space created there between.

16. The automated cat litter box of claim 12 , wherein a hand crank positioned on the outside of said cabin provides means to manually drive said cleaning carriage.

17. The automated cat litter box of claim 2 further comprising four circular grooves at its corners, wherein pins positioned on the cover of said litter box snaps into said circular grooves to hold said cover in place.
