Poor Luna. It looks like she may have created a skin infection behind her right ear. We will commonly see cats create wounds from scratching at areas. I would recommend having her evaluated for an ear infection and to evaluate for any secondary skin infections. If there is an underlying cause for her to scratch that area (ear or other skin problem), you will need to treat that underlying cause first in order to allow that area to heal. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
