Probably not weird at all - the licking part, that is!

My big orange kitty Murf (RB) had a "sweet spot" on his spine near his hips - when anyone scratched him there, he would bliss out and let his eyes go crossed and start licking anything nearby. It was a very funny sight!

My kitty Winston always wants to lick me while I tickle him - mutual grooming, I think!

As for the dandruff - he might need a different cat food to help with his skin - or maybe some extra brushing....

Good luck, and welcome to Pet Talk!
