Unfortunately I'm at work so I can't stay on...but, does Lucy seem to feely icky in general? Do you have any babyfood on hand to try? If you try baby food, you want to be sure it is straight up meat and nothing else - no onion, garlic or any veggies. Some kitties do like it when they aren't feeling well, and since it's bland, it's easier on the tummy.
If her tummy seems upset, you can possibly try giving her some Pepcid. You want the most basic Pepcid AC - 1/4 of a 10mg tablet.
If she continues to not eat, you may need to call the vetty.
Hopefully someone with more experience with inappetant kitties will come along soon....please eat, Lucy!
