the cat’s just playing :) it’s having a very good time, & seems to have a great relationship with the sleeping dude. I’ve had my feet preyed upon similarly on many a morning!
it’s always good to break down body language, but swishing tail just means highly stimulated, and Attack posturing (arched back/pinned ears) is super normal in playful animals.
not to dunk on them or anything, I get why they’d build this narrative, but the tastefullyoffensive caption is deceptive because it implies an anger-fuelled motive.
