Re: cutout comb
I find masking tape to work quite well. Just put the comb within the frame and wrap the tape around the comb and side bars horizontally to hold it inside the frame. Then wrap a couple of strips vertically, going around the bottom of the comb (not the bottom bar) and up and over the top bars. This holds the comb against the top bar so they can attach it to the bar. In a few days they chew the tape off just like they do with rubber bands. I prefer the tape just because I can never find rubber bands just the right length.
