Sounds like Kuhio's last year (she lived to be 17 years and one week). She was diagnosed with a hyperthyroid. She wanted to eat and drink a lot but almost always threw up. She was down to 6 pounds and towards the end I would grind up the cat food with water to make more of a soup. She loved lunch meat and cheese so I'd mince it up as finely as I could and her favorite thing of all was any meat baby food. We let her eat any thing she wanted because we were desperate to keep weight on her. Right up until the end she was happy and active and in no pain. Grasshopper is in our prayers.
