Thank you for this article! I just got my baby and she licks her paws sometimes, and scratches her ear, tail, and rubs face on carpet too. I'm starting to think she has allergy but I did not see red moist skin and her ears are very clean. Her chin and around nose area are pink tho. IDK, I'm a newbie on pet and just couldn't identify if she has allergy or I'm too paranoid.
