This is my first time to this site and I was wondering if anyone has/had a cat with the same problem mine is having. About a month ago, we noticed that under her chin, she developed something that looked like "dirt". Most would come off when wiped with a wet towel, but would not completley go away. The problem has become worse. She is now scratching and digging at it, making her chin bleed and it is not going away. We thought this would be something that would pass on it own, but it doesn't seem that way. I would like to see if anyone has dealt with this and what it could possibly be, before taking her in to the Vet. She is a long haired Calico, Just incase that info is needed. Thanks in advance for any help you can give.
