Vet Visit For Feline Acne of The Chin

I did take Abby to the vet for the feline acne on her chin.  Looked like a wound developed right by the opening of her mouth but on her chin.  She didn't get sick on the way to vet as I didn't feed her for six hours.  The vet said it looked like a mild case of acne and gave me an ointment to apply twice a day.  Abby won't let me apply it.  Again, I waited and it healed up, not completely but it just looks like a black spot now.  I will keep an eye on this as well as the new spot on the top of her head where she is scratching and causing a slight wound.  I tool her to the vet Thurs 9-2-10 for the Feline Acne problem.
