Well, we were told she was eating hay and throwing fits about being cooped up, so I went to pick Tidbit up today. Upon arriving home, she went into a corner and has refused to eat, drink, or use her litterbox since.
It looks like she pulled a fast one at the vet's in order to get sprung. She's not fooling us, though. Unless she makes some progress with either input, output, or both, it's back to the vet for her in the morning.
With our vacation starting in just one week, we're starting to have to think about contingency plans. Once I start my new job, I can't take vacation for six months, and Dan won't have another opportunity until December. If this rabbit doesn't start eating, we are so screwed.
