My 14 year old American Short Hair has three spots on her ears and now one on her forehead where there is light hair loss, and in the centre is a small red dot like blood congealed over an insect bite or sting.
I took her to the vet's last month, and even though one spot still had the dot remaining he said it was nothing in particular and just wait for the hair to grow back. Since then two more spots have appeared, so what might be the cause?
She's an indoor cat, but hadn't recently been treated for fleas etc.
(I've since used Broadline, but that caused a 5 cm diameter bald patch at the application point!)
