I would be incredibly wary of this, just because I had an almost HORROR story with my precious little baby, Coco. She was wearing a breakaway collar that didn't breakaway as it should have, and while I was sleeping one night, it got caught on the cord for the mini-blinds that she had batted down from where I kept it hung out of reach. *Something* woke me up, and she was hanging there choking. I managed to free her in record time and she was just fine, but both of us were shaken up quite a bit. Ever since then, I have been nervous when I have to put her collar on her...and I only use the super lightweight ones that have good breakaways on them. I would die if anything happened to her!
