The steam caught her attention and she leaned down a little, peering under the bench from across the room. Not an easy task, but whatever it was was dark, and not easily recognisable as either dog or cat, so she figured it had to be something else, and the floor around it began to frost over rather quickly, a circle of frost, thickening as it closed towards the creture's claws. Oh yes, she could see those.
"I don't know what you are, or why you're here, but I suggest you leave," her very tone was ice, the steam caused by her breath dropping to the floor as tiny flakes of ice as the temperature dropped even more. She was glad no-one else was in the laundry room, although she felt fine it had to be approaching freezing despite the machines.
