It could be a flea allergy Mark
Three years after I had my infestation cleared, Misty had these weaping patches on His head?? so I took Him to the Vet
and she said it looked like a flea allergy causing his scent glands to weep, they did look red and sore, but they didn't
seem to bother Him?? the vet did say because He'd had fleas before, he may well be alergic to them, and that it would
only take one bite from a flea to kick it off ( Hamish was Fine and so was I
)
I think they gave him some flea treatment or antihistamine injection ?? and it soon cleared up
Sending Clapton some get well soon Vibes
