Cat has something in her ear.

Hello vets, I noticed this on my cats ear yesterday and today her ear looks like this. Does anyone know what may of happened to her and what this is. Thank you in advance for your help. 🙏

Hello - is your cat losing hair around that area of the head?  If so, please go and look at the other very recent post about hair loss on cats' faces.  I do not recognise the lesion but Ringworm should also be on the list, along with all the precautions associated when Ringworm hasn't been ruled out - this may include wearing gloves to handle the area.  Because pain and infection may be a factor, please ask your vet for triage in order to establish how quickly they may wish to see this patient.  Please will you let us know what they find?
