My cats have always licked me - I've always considered it a sign of affection, My 8 yr old (nearly 9) licks me quite a lot and his brother (who died last year) did the same. In fact Magpie (the one who died) used to bite me when he was a kitten but if I kept my hand completely still when he bit he would start licking. Jaffa (my 8 yr old) holds down my new kitten and licks him all over,
