Something I've just remembered: a week or so ago, before the spay, I found some fur she'd pulled out in a pile by her cage; she's also shedding, but this was quite a bit, and because it was white and I couldn't find any bald spots, I assumed she'd plucked some from her dewlap/chest. And now earlier, when I went to give her the painkillers, I found a similar though slightly larger pile by her cage again, white and fluffy. Not sure where that came from; could she be taking some from her tummy due to discomfort, or something?
