When Momma first got us the automatic litterbox, she was very impressed with my inventiveness. I used to jump in out of the litterbox to watch it move. Then I tried doing the same thing with the other litterbox and I was so disappointed that it didn't move around at all! Oh well. She thought I was very smart for thinking of that.
I love that litterbox because not only is it always clean and stuff but I can play with it. Georgia likes the ramp.
