Since I knocked him out cold last week he's been giving me the old hairy eyeball, but staying clear. I've out of the blue chased him a couple times to reinforce the lesson and this morning netted him. He's too heavy for me for pack around for long, but I held him for about 10 minutes, then tossed him out on the lawn. So far so good. Hopefully if I keep up with the intimidation he'll stop attacking.
