The female radix I have seems to like pinkies and not fish. However, she has regurgitated pinkies a couple of times. First time was last week when she was in the the RUB on paper towels, and I think I spotted it shortly after she brought it up and removed it.
I've just found two pinkies that have obviously been regurgitated in the last hour or two (I had her out a couple of hours ago and they weren't in the viv then). She ate two whole pinkies on Saturday afternoon. The odd thing is that it looks like this isn't the first time these have been brought up, one of the pinkies had dried a bit at some point, making me think it had been regurgitated then re-eaten after it had been out for a bit. The other strange thing about that pinky is that the head was hollow, like the brain and skull had been digested. The other thing that made me think they'd been regurgitated, re-eaten, and regurgitated again is that there were bits of substrate (aspen) on them that looked like they'd been pressed in hard and discoloured.

Couple of things:
- is the skin the last thing digested?
- the pinkies have been in her for 3 days, should they be so intact still?
- is repeated regurgitation a cause for concern? I'm aware it can be a sign of an impaction, but I assume there are plenty of other causes.

My plan is currently -
I'll try her on fish again tomorrow, if she doesn't take the fish I'll leave her for a week or so before trying her again. I'll only try her on pinky again if she refuses fish a couple of times, and if I do it will be a single pinky and I'll probably cut it open a little in the hope that it helps her digest it.
