Our cats do a lot of this, too, particularly the slow-motion slaps! They're littermates, though, so there's definitely no mothering instinct going on. And they're both drama queens in their own ways.
Haha, yes! Our Anya is the queen bee around here (I say that, but she doesn't have a bad attitude or anything) and likes things in order. It is rather hilarious when she "beats him up," which is of course over-dramatizing it since it seems rather playful. She likes to bop Alexei up side the head when he steps out of line. It's a slow motion slap too. I think it's a motherly instinct or her just being the older cat because she also grooms him while he sleeps and seems to comfort him.
I love that your cats have Russian names, @coquelicot!
