Hi all.

Zee B, my 4 month old black moggy seems to have a problem with one of his
ears.

It is going to be difficult to try and describe it, but here goes ....  His
left ear flap seems to have developed a raised arch, sort of like a ridge
that follows the tip of the top of his ear on the inside.  Also, there are a
few raised patches further down the ear flap too.

I have done some research on the net, but all I found is ear mite, but there
is no dark discharge & he isn't scratching his ear or shaking his head. .  I
also read about cat allergies and am wondering if this could be the cause.

Does anyone know what it could be ?

TIA
