As I mentioned in my last post, Mac's bosal needs to be shaped to his head. It should fit like a hat - not tight, but with even contact all around and snug enough that it wouldn't just fall off his nose if there weren't a hanger there.
I took a romex wire and measured the shape of Mac's nose. Then I traced that shape onto paper. You can see how his nose is narrower than the bosal.
I laid the bosal over the tracing for a better view.
Being the wonderful, fabulous husband that he is, Colin took the tracing and shaped a wooden block for me.
You can see where the gaps are on the sides. Colin was also kind enough to lend me one of his hockey skate laces, which are very long, to tie the bosal to the block. The requisite cat inspection is evidenced below.
It has been a couple days now, so I'll untie it tonight and see how it fared. Unfortunately (or fortunately, because we are in a drought), we've had so much rain that I haven't been able to ride since last time (well, that's an obvious statement) - almost two weeks now. I've got a few days off from work coming up so hopefully the weather will cooperate and I'll get back to my training!
