Hi Dianne,
I'm sorry to read that Savannah hasn't been feeling well and is reluctant to eat. I hope you and your vet can get her healthy again. The food tips you got yesterday may work. A sprinkle of FortiFlora usually works because it contains "animal digest"--one of the principal ingredients in dry food.
Hang in there. Lots of healing and eating vines on the way,
Ella & Rusty
