Well I had a look at her "hands" and didn't see anything resembling a pad (not that she was cooperative or anything - and yes I got peed on), so based on size and all that, I'm willing to bet Diglett's a female.

She hasn't eaten yet, I've offered her a small mouse and some large locusts, but she didn't seem interested, but she is due a feed, so I'll leave her for a few days and then try again

All hail Diglett.
