Thanks everyone for the prayers. Please keep them coming. The vet just called. Grandma will get to come home around 5 tonight. Her kidneys are getting worse but they aren't too bad. She thinks that it's Grandma's thyroid that is causing the problem. She had lost a bit of weight since she was there in October.
Her thyroid then was 3.2 now it's 5.6. So they are going to start her on a thyroid pill and give her some kidney friendly food. They hope the thyroid med will stimulate her appetite and she will start eating. If she doesn't eat by tomorrow night, I'm to call them back. They feel she is more likely to eat here than she would if they kept her.

I just hope she will eat the food they send. She is sending that KD food. I've never had any luck getting my cats to eat that stuff.
