I thought I'd give you all a bit of an update.
I've seen Cora a fair few times since her last due date and she's certainly looking slimmer. She's got quite an appetite on her and is not keen to be away from the nest for too long of a period of time preferring to come out for short frequent visits to get food, scurrying back fairly quickly.
She's been quite clever with her nesting skills, moving the entrance tunnel to her nest every couple of days... there's not much chance of anything escaping from that nest if Cora has anything to do with it.
