She's a young saber-toothed cat. We had an infestation of them a while ago and I think someone killed her mother.

[ Oh, he's very aware of what she is, but no one's bothered to tell him that it's a bad idea to keep paleolithic animals as pets. ]

We set up a shed for her for the snow, but I wouldn't invite her into the house. She's small now, but I imagine she'll break everything once she's bigger.
