Thank you both for responding,
i didnt mention CM os i had never heard of it, its only when you mentioned it i panicked...then Mike read the report from the vet and saw it mentioned. So when i read your response i mailed him, snd you saw his reply.
Charlies scratching really is mild and stops within seconds if i tell him to, if he chews his foot he again stops immediately and only does this not even once a day.
but we are going to our local vet with the report and cd,s and see what he advises..again thank you
