This is the second time I've noticed some small scratches/cuts (dried blood) on the outside of my cat's ear. She's an indoor-only cat, so it's not that it could've been caused by another animal. Could it just be that she's scratching too hard? I don't think it's ear mites, because I've looked in her ears and they seem clean. She sleeps with me at night, so if it were fleas, I'd probably notice by now. I'd take her to the vet except she is extremely opposed to being handled by anyone but me (she has to get sedated for her vet visits).
