It's done, Joey was snipped today. Vet charged me $80 and he got to keep all of his ear. The OSPCA would have charged $67 so that's very little difference.
Got him in the trap this morning, sure we are the only source of food he has so he had no food since last night. Slit, snip, a bit of tying off inside, no stitches, he's back home in our garage where he has a warm house, food and water.
