Quick update - Binky finished ate the rest of the pinky I left for her overnight, it must have been around 6:30am, as I got up to shout at the cat (who had woken us up and was up to no good downstairs) at 6:00 and the food was still there.
She's been out a bit today, and has been poking her head out a bit more. Still cautious, but her curiosity may be getting the better of her now.

Looks like we're on our way to being hooked, trip to the breeder meet in Doncaster on the cards a week on Sunday.
