Thor's not really all that fond of the new snow in his yard. He had just gotten accustomed to his feet not getting cold when he went outside.
In all fairness, we got 9" of snow, but only about 4" appears to be in our yard, so there was plenty of melting during the 24 hours of snow.
So Thor's doing a lot of sleeping.
But Thor's no dummy; he always poses when he hears the camera.
