Not happy. Been away for a few weeks and had left the cats at the cattery we always use. Picked them up this evening and noticed when Jazz was eating his dinner that he'd managed to get his foot through his Bioflow collar. I tried unbuckling it but he was clearly unhappy so I had to cut it off. To my horror I realised that the collar must have been stuck that way for quite a while. It's dug into his skin pretty badly under his armpit, but the worst area is his chest where the buckle must have been. A large area of his chest has been skinned and part of the area is an open, bleeding wound. I've cleaned it up with diluted salt water and he's currently got a buster collar on until he sees the vet tomorrow. My question is, would you hold the cattery responsible? The collar's black and so is he, so perhaps it just wasn't seen? I'll try and upload some photos of the wound.
