I took her out after leaving her alone for a few days and I now think that I may have solved the riddle: that old familiar bluish haze is upon her. I'll wait and see if she normalizes after her shed.

Interestingly, I held up her food dish as I was holding her tonight and she actually b-lined for it. Didn't eat anything of course, but the fact that she thought about eating while being held and shedding was cool. I have a feeling she'll be a little hoglet post-shed.
