Unfortunately I don't remember what caused the scab the first time.. it's been at least a year ago. It's not inflamed at all.. Noodle's not bothered by it. She doesn't even mind if I touch it or brush the loose pieces off. It appears to be healed underneath as well. I am going to investigate the "hot spot" idea though.. it's something I've never heard of.. thanks for all your help! You all have cute kitties as well
