Well hopefully it's not an RI, only that some shed is remaining that's causing the trouble. Raising her humidity, you should be able to help her finish her shed, & if you
just walk into the vet (with the dried-on shed), he or she won't have time* to do that sort of thing anyway, at least that's my guess. *Or it will cost a lot for something
you can do at home? If that was me, I'd have held off on the feeding so as not to have a negative impact on her digestion, but you should be able to contain** her with a
very damp towel for a while...maybe in the cage where it's plenty warm, so she can "multi-task"- digest & clear the old shed off in peace- then help manually after all the
old shed is moist & easily removed, if any is left. **By "contain her with towel" I mean in a smaller plastic 'critter cottage' that she can just fit comfortably in with towel.
Has the humidity in her cage been too low? This really sounds like a home/husbandry issue that you hopefully don't need a vet for?
As far as her recent meal, it should be mostly digested by now. You aren't still seeing a bulge, are you? For future reference, don't feed items that are
larger than where they are going (her mid-body- stomach); slightly less in width is preferable.
