Stray Kitten in the Workshop

This little stray kitten has been hanging around the workshop eating bread-crumbs left out for the birds. It runs away when I approach it. I Leave it some food and I can tell that it eats it by the footprints. The snow is too deep for it to forage farther than the compost-heap. The snow is so deep that all the animals have bedded down. At 15 degrees below I don't see how it can survive.
