Hi! If someone could help me, I'd appreciate it. I have two cats. One is perfectly fine. The other is a short haired black cat, and he seems perfectly healthy (he plays, eats like a champ, etc) but he has been getting some light bald spots on his head and around his ears. The spots are white and there is no redness, oozing, or scabs. He does groom frequently, but I don't think it's too much. Their both indoor cats and up to date on their shots. Could someone please help me figure out if these spots are an issue or not? Thanks!
