Do think that xeno au vampires would when they feel like they are not getting enough attention act like cats do and mope around near you or do increasingly annoying things to get attention?

-Yes, it’s quite likely. The bonding instinct, one of the few pro-social behaviors that vampires have, demands that they stay in the good graces of who it is that they’re attached to. In the same way that heartbreak from losing a friend or lover hurts humans, feeling rejected or separated from the bonded person is very nearly physically painful. It depends on the vampire, but nearly all of them would wind up doing what you described if they got desperate enough. In the case of our boys, especially the “increasingly annoying things” part, because they’re all children who don’t know how to ask for attention.
