I'm so sorry about your friend Bobby

I wish you were feeling better. Are you still taking the doxepin?
Can you try eating things that are gentle on the stomach such as applesauce, white rice, or toast?
I hope you start to feel better soon

What beautiful cats! How old is she Bobby?
It's common for them to hide when they come to a new place. She will start coming out for longer periods soon. There are other cats, so that might be a factor. Are the other cats showing any interest?
