I don't know how long he had been hanging there in pain, twisting himself around the wire, but when I found found him he was just about done in. He still had a bit of fight left in him though - my hands are shredded as a result of his determination to fend me off. Had to take off my shirt and wrap it around him till I managed to unhook him.
He's currently curled up under his very own tail - about the length of his body - all six inches of it, and I have to say it's awfully tempting to keep the little critter as a pet now that I am completely attached to him, having spent a couple of hours stroking his incredibly soft furry body to relax him enough to be able to get at the wounded skin and slather it in betadene.
He actually ate and drank after sleeping it off all day, so if the torn skin looks clean and there's no infection, I'll let him go tomorrow night. But damn, humans are cruel bastards. I had no idea these little creatures end up tangled on barbed wire. Now I'm going to have to do a morning patrol along the fences that pass through bush land on the farm - which is just about everywhere.
Oh well, I can do with the exercise, and it'll save G-Man the hassle of looking for broken strands. I suppose I could probably take a roll of wire with me and the fencing pliers as well, as if there isn't enough to do around the place.
