Hi, my 2 year old ginger Tom has a white, sort of flakey/scabby ear on the tip and inside. It is very dry to the touch. Just on one ear. He is up to date with all flea/work treatments etc. He seems fine in himself - eating, playing out, wanting his usual cuddles - the only thing he is unhappy with is when we touch the ear at all, he shies away. He hasn’t seemed to touch/scratch/attempt to clean the ear himself. I’ve attatched a few pictures. Any advice would be really appreciated. I’ve had many cats before all whilst growing up and never seen this before!
