@Katfarmer,
The name of the food was "Max Cal" I think it was by Eukanuba. (only purchased at the vet)
I am glad to hear it was something gradual so that pretty much rules out the need for a US to determine if it is fatty liver.
The prednisone should be making kitty hungry, but I think it should be given about a half hour to an hour before she normally eats to have the proper effect. (my expereince with giving it to one of my kitties)
You could try Stage 3 baby food. I had a kitty who would eat and eat and eat it as long as I fed it off a spoon. If I set it down, he had no interest in it.
You might also try adding gravy, bacon grease, or oil to her dry food. My kitty prefers it to be warm also.
Elsa Shmeltza Cinnamon Toast..wow that is a very unusual (and terrific) name!
What a great name!
