So shows up on Saturday night in her roo and has a bunch of cool things in her pouch, a muzzle was one of them.
After a bit of struggling we got it on her and it was Murr.

She then says (after the muzzle was off, big mistake... roos need them all teh time) She said that it was a whole lot better if you were gagged with a sock first, then have the muzzle strapped on. So I tried it.
It's very effective at keeping the roo quite quiet... sock gagged and muzzled....

I need one now...
