I think I found the problem with Mike's ear. He finally lets me pet him again. This morning he let me look at his ear. Looks like he was in a fight and that ear has been hurt at the outside base of it. It was infected. I washed it out with a cotton ball and warm water. I didn't put antibiotic on it because he might be able to wash that off with his paw. Don't want him getting sick from that. At least now, maybe he'll let me keep it clean.
