There was a little cat that used to accompany me on my walk home from work most nights. I would walk through this pretty quiet neighborhood, and the cat if he was outside would run up and walk along with me. Like "Oh shit, we buddies, let's go on patrol together." Eventually, it would be too far and he would take his leave. Then, same thing next night.
Wonderful stuff, man.
This is a remarkably good list. I know you're getting a ton of recommendations OP, but this is really a very comprehensive one with an absolutely excellent balance of "real good quality" combined with "easy and rewarding to watch."
