I've had a few, and most of them while I lived in CA.
I had a couple of black bears cross the road in front of me when I was riding my MC. The bears were not inclined to be sociable, and neither was I, so we went along our merry way w/o incident.
I had a squirrel fall/climb down my chimney (covered in soot). Fortunately, I had a folding glass plate in front of the chimney, and it was closed. When I realized the situation, I opened the front door, opened the glass plate, and stood on the opposite side of the living room from the door. I was hoping that he would be attracted to the sunlight and trees, and not want to have anything to do with me. He chose the sunlight and trees. If he had picked the other option, I would have had soot all over the inside of my cabin.
Had some visiting raccoons. Had one that was on a portion of my roof with a shallow grade. I started throwing peanuts at him. It was funny watching him chase after the peanuts, before the peanuts rolled off the roof. He had about a 50% success rate. Fed another raccoon a steak bone. When I saw his nasty teeth knawing on the bone, I realized that if I keep feeding them, nothing good will come from this endeavour.
I was walking my neighbor's dog, and she ran down the slope, out of sight. I heard her barking, but it didn't sound like barking. I had never heard this sound from her before. It sounded like she was half happy, and half confused, so I walked over and looked down the embankment. I saw the dog and a coyote. From appearances, the dog wanted to play, and the coyote wanted dinner. It was a good thing that there wasn't a pack of coyotes...............
