Oh dear, boop the cuties.
That really depends on the little in question. For instance, Bree isn’t going to mind one bit. She’s used to contact with humans, and considers it completely normal. Oscar, on the other hand, has never really had close contact with humans and is always baffled when Dean insists on messing with his mousy hair.
Dean as a little will be completely offended that someone is messing with his spike, while Sam is resigned, considering how often Dean fluffs it into a mess. Dean’s way of saying you should really cut this.
