So, I have been going up there daily since I got the news. Thankfully, she has put some weight back on. I was completely horrified when I first saw her, she was so thin. It was very frightening. Her owners are still 'syringing' her the warmed up kitten food with the meds, but as she's eating from the bowl now, they will start to crush up the pills in to her food.
We are not out of the woods yet, and she has to go back for blood tests in 3 weeks. I was with her for 5 hours today and even had a little jaunt outside in the garden as the evil doggies have gone away for the weekend so she has the house to herself. I even gave her 2 helpings of roast chicken from the rotisserie and she ate it all up! It will be a slow recovery and I still feel on knife's edge so to speak, but we are getting there.
Thank you all for being so supportive and providing the purrs/prayers.
Here is a pic I took a while back:
