Automatic Litterbox Central

national geographic channel had a great show on recently called Unlikely Animal Friends. if you didn't see it, you can watch it by clicking the link. It is sooo good. There is a segment about a kitten and a crow who become best friends. when the cat goes inside to live with people, every day for the next 4 years, the crow would come to the door in the morning and wait for the cat to come out. They would play together and hang out all day.

All of the segments are incredible to watch
