Found in early November 2019, Hoggy weighed a little over 300g and so could never have survived the winter.  She was brought indoors and has her own winter quarters with personal electric heaters keeping it at a constant 19^o centigrade.  Hoggy has steadily gained weight and weighed in at 681g at the most recent weighing.  The trick now is not to let her get fat before releasing her in the spring.
