Thanks for using Petco Pet Education Center, formerly Petcoach! This could be an infection just like you pointed out though I am more suspicious about something called an eosinophilic granuloma. I recommend that you have Missy evaluated by your veterinarian for further assessment and treatment. Both of these conditions are treated in a different way so being able to diagnose would be good for more accurate and direct therapy. Good luck and have a good day!
