She ate her dinner and is sleeping now. Her appetite and digestive functions seem normal at least. I think part of what is driving me crazy is not knowing what is causing it too. About the same time as the different food, the neighbor's tree dumped a load of leaves that has just covered my back yard including the deck, and I did notice today she seemed really exacerbated when she came in from outside. This is a different area and it's conceivable that there are pollens and irritants in the air that we didn't have in Minnesota or at least in the area I lived.

I am really hoping I see some noticeable improvement by morning. It does seem like it started out with just her licking and chewing her feet some and progressed more and more which would probably fit the environmental allergy picture more.. I just don't know. I can't seem to stop obsessing over it at this point either.
