If the fuzzy is less than ~1.5x the widest part of her body she'll be fine. Can you pick some up at a local pet shop or something?

Two weeks w/o food isn't hurting her. Another two weeks won't hurt her either. I wouldn't recommend to do this on a regular basis, but if its another week or so before you get food, I'd just wait.

You definitely don't want to feed her something too big, and cutting up fuzzies is going to be a huge nasty mess.
