We got this muzzle after Lucy attacked one of our smaller cats last week. We are hoping we don't have to use it often (she was resigned enough about it). Certainly, she can't get at anything more than water and a few small pieces of food (no kitty parts). It's a safeguard, is all.
The good news is, she's been an angel since the incident. Really, quite good. I've been reading a lot about canine aggression (an extensive article courtesy of our vet) and I really do not think she has a serious problem. Hopefully, this means that we might be able to keep her after all.
Don't worry all you Lucy fans; the muzzle was on her for about 10 minutes and that is it. Long enough for me to ascertain that a) she'd allow us to put it on her b) she wouldn't completely freak and c) she can drink/breath easily.
Oh, and of course I had to take some pictures. She really did look quite pathetic!
