Itchy face!!~UPDATE #8

[pomtzu]

I'm stumped, and thought perhaps that someone here might have an idea what's going on.

Myndi has an itchy face, and is constantly rubbing her face on the carpet, or even worse, the bed half the night when I'd really like for her to be sleeping, so that I can sleep too! She scratches at her face too. She and Sparky always had seasonal itching, and probably some due to food allergies too, and I changed them to a no grain diet a couple of months ago. It's the Veg to Bowl - the same thing that Freedom has the fluffs on, and it has done wonders. No more itching and chewing themselves, Sparky's goopy eyes cleared up, and their fur is in so much better condition - nice and soft and silky. This face thing started about a month ago. I checked her ears and cleaned them, so that's not the problem, unless there's something further down that I can't see. I noticed that the skin above her eyebrow was a little reddened a couple of nights ago, but that's back to normal now.

I made her a vet appointment for Tuesday, but in the meantime, does anyone have any ideas? It's just so strange that it's only her face.
