What’s this on my cats forehead?

Can anyone tell me if this is just a scratch/scab? It’s a couple days old. 

Hello!   It looks like a scratch or scab by the eye, but theres no such thing as 'just' a scratch or scab;  the question is, what has caused it?  The answer is that anything that might break skin like that on a human, could do the same on a cat.  Fleas tend to cause self-trama, so that could be related;  a scratch or barb from a cat, fence or plant matter;  allergy; an old scab falling off;  possibly the start of ringworm or folliculitis eg from demodex; an infected hair follicle; also scratching at a painful eye or sinus for example.  A sore part of the ear looks blurred - could that be a lump?  Its hard to tell out of context.   Usually, small scratches scab over and dry up, but cat fight wounds (teeth or claws) tend to get infected and swell.  More sinister causes for lumps include cancer.  However, depending on the underlying cause (such as infection or demodex in an immunosuppressed cat, cancer if a follicle is swollen, endocrine disease), it may prove serious.  If that is a lump at the base of the ear, it might even need to be biopsied.   It could also be possible that Ringworm is present, so be careful in the event of immunosupressed people being around, just in case.   You may be unsurprised to learn that I think you should let your vet check this over, especially if it is a new change.

Nb should say:  cancer of the follicle if swollen
