He's happy just standing there too, fiddling a little with the controls, until he suddenly spots a kitten at the top of some stairs.

"What?!" he exclaims, letting go of her to run over to the tiny cat. "How'd it get in here?" he asks, picking up the kitten. Granted, he knows by now that they're not regular kittens, and that they seem to appear and disappear randomly quite a bit, but beyond that... It certainly doesn't explain how one could get inside. That should be impossible.
