Thank you for your reply. There is no redness, my husband thinks it is his skin pigment, but I have been thinking it is some kind of dermatitis or a mite, Claudius is not in any way bothered by this, and is not scratching ..
I will have to take him to my vet for him to confirm your ,prognosis as he may need treatment.
Thank you again.
Thank you for your kind accept. I appreciate it.
