I promised Fui I would only show him from his 'good' side in this post. This all happened 3 weeks ago, and he finished his medications a week ago. Luckily it all healed up nicely, and so far his chin is still looking good. He does have a few bald spots. We're watching him like hawks and making sure his chin stays clean. It was a good reminder of how quickly things can get serious with kitties as we hide things so well. Hopefully we will be able to avoid a recurrence. Paws crossed!
