Thanks Le Ann. She came out for a few minutes an hour ago so we're not so worried, but headed back for cover when we got closer... I'll get some photos soon I'm sure.

I've read through the care sheets (and a lot of forum posts... trying to learn quickly), the bit it doesn't cover is how long it's normal for them to disappear for a whole day. And it's inferred, but I'm not certain whether we can safely leave her unfed for a couple of weeks. And how often do they need to drink?
So many questions... you think you've read what you need to know, then when you have one you realise that there's still so much you don't know.
