Thanks for the responses everyone! It is good to know this is fairly normal. Sounds like maybe she still doesn't feel 100% secure in her new home, but I'll take slow to swallow over a refusal!

I think it was bigger than before, by a larger margin than I thought just by looking at it. Or at least there is some reason why she has stayed in her hides even in the evening since she ate it. Usually I see her out & about in the late evening, but not these past couple of days. She is switching from one hide to the other though, so I assume all is well except a full tummy.
