Collar wounds again

This story does have a happy ending because the cat's microchip enabled us to trace her owners. She had been missing for nearly nine months and they had given up hope of ever seeing her again. However, they are now going to be faced with a pretty substantial bill at their own vet as the wound caused by her collar will need cleaning and stitching under anaesthetic, and possibly a skin graft because so much of the skin around the area is infected and rotting. She's otherwise well and is eating so has a good chance of surviving and not losing the damaged leg.

All cat collars are potentially dangerous because the cat can be caught up and hung, or put a leg through the collar and slice into the soft skin where the cat's leg and body join. The least dangerous kind have a fastening which is designed to click open if it is put under tension, but this may not work if the cat is small and light or if the fastening is glued together by mud or food. Flea collars are the most dangerous because the wound they make will be contaminated by the insecticide with which they have been impregnated, making it even more difficult to heal.
