Loki hadn't actually considered being a kitten around anyone other than Stark, but it might almost render things closer to medical. Therapy kitten! And this time, when he wanted to be a person he didn't have to sneak. Unless he felt like it, which he often did.

Almost absently, he wondered if Valkyrie liked kittens, but got distracted within the first second or two by batting/shoving at Stark's thumb in his face with tiny, ineffectual paws. That was going to be a pleasant daydream! Stop!
