That's a great idea!What about just wrapping the neck in vet wrap? (this sort of stuff <<link. I dont know if you guys call it the same thing over there!) It can rip under enough pressure and can be wrapped as many times as you want thick. It is cheap and can be reused to a point, but to prevent infections I'd be inclined to change it daily.
Goodluck! Its not something I have ever thought of, right now my boys are separate from the girls, and those little hussies are crying about it haha.
