Snow Approaching

There is a rumor of snow fast approaching, and we are concerned.  What if the power fails?  This snow is due over the weekend, when the grandhuman will be away at work for hours!  If we loose power while she's not here, the human will have to call a cab to evacuate with us to a warm hotel.  Do cabs charge by the passenger?  And if so, is there a discount for bears, bunnies and assorted other teddies?
