Rocky was my border collie. He was the smartest dog ever, and he was somewhat psychic, too.
He loved to play with the cats & kittens (we lived on a farm back then, in a land far away), and would play "king of the hill" with the tom cat on the rock in the front yard. He would take his turn being "dethroned", too. He also played frisbee with himself when he was bored.
When I got my divorce, I cried because I had to give up Rocky. I found him a home with someone in South Dakota, I think it was... larger farm, lots more room & animals for him to enjoy romping with! That was long enough ago I'm sure he's traveled the rainbow bridge by now, but even so, he was the best dog.
