The ornamental design for a kittylitterbox, as shown and described.
FIG. 1 is a perspective view of a kitty litter box showing my new design,
the top flaps are in closed position;
FIG. 2 is a perspective view showing one top flap in open position; and
FIG. 3 is a perspective view showing both slaps in open position.
The box liner and cat shown in broken lines in FIG. 3 are for illustrative
purposes only and form no part of the claimed design.
The rear and bottom views of the kitty litter box are not shown. The rear
view of the kitty litter box is symmetric with and substantially identical
to the front view of FIG. 3, having no additional ornamental features
therein. The bottom of the kitty litter box is flat (as shown in cutaway
in FIG. 3) and contains no ornamental features therein.
