Glad to hear that Jack finally provided you with a sample!
Ah yes,... the muzzle. My cat Stinky once had one strapped on by the vet when she went 'crazy' during a visit a few years back. It looked like a tiny Hannibal Lector mask. Yikes! LOL
It stressed her out so much that since then I just do everything possible under the sun to avoid taking her in if I can because I hate to put her through that. (and the vet and me for that matter!) Thankfully the muzzle was only brought out once but it certainly was a memorable experience.
