My squishy boy Smokey has got what looks like pale porphyrin above his whiskers. It actually looks kinda like he has pushed his snout into a compact or something. He's nearly two years old, and he is pretty OK health-wise.
Should I take him to the vet, or just keep an eye on him? We had another boy with porphyrin that came when he was dying (he had a tumour

), Smokey is nothing like as bad as that which is why I am not sure what to do... it doesnt seem bad but it didnt use to be there.
Thanks for any advice!
