Thank you to all.
Arnie came from Becky's RSPCA Walsall branch. If there was a way of getting into the kind of trouble to put a smile on your face he would find it.
Sadly it was Teasel who taught Arnie how to chomp through wooden frames to begin peeling the wire up. As Becky had him when he was a little tiny kit he had no reason to suspect that life could be dangerous. Had another look early this morning. His prints were heading straight towards the large strawberry pot. He loved strawberry leaves so my guess is he made a break for it to raid the strawberry plants he knew where there somewhere. Hopefully he never knew what hit him.
Teasel is sat munching away and looking more relaxed this morning. She is not looking for him so I think she knows he is dead.
Once I can get out there and tackle the run and replaced the chewed section; husband is sat next to me this morning reading up on how to turn the yard into fort knox with electric fencing to keep foxes out and buns in. Then we can consider looking for another rescue buck. For now Teasel can have the run of fenced off section of the litchen.
