Aww thanks for all the replies everyone!! Last night I had Saxon inside by himself (for a change!) and got him to sit still and I had a good look. It's a little patchy, and just on the part where his ears fold over (it's on the outside, not the inside). He let me touch them, they felt a little warmer than normal. The only thing we had in the house was Vaseline so I put that on and he gave me a big kiss on the cheek after that, so it must have soothed his ears! Then I cleaned the tear stains from his face and he is looking a lot happier! And I haven't noticed any more flies since I put the Vaso on!
