Hey everyone, Nemo (the cat) has been getting these hairless bloody patches, generally on his head, for a couple months now. Because we have three strays hanging around, we assumed they were injuries. They've always seemed to heal. However, this time it got worse. Maybe hotspots? You can't see it in the pictures, but his chin also has a bloody spot. It's in the exact location of injury from last year that scarred up and looks like it was re-opened. He doesn't uncomfortable in anyway and he can't lick the spots. If it is just an injury, I think we'd put antibiotics on it and take him in if it gets worse (since it doesn't look infected). If it's a sickness, we'd take him NOW because of his and the other pets' safety. Please let me know. I do not want to make a pointless vet trip, but I don't him to make him suffer.
