Well I went to see her yesterday and she is depressed. Her BUN was
only down to 115 from 123. Dr.  said she seem much more down and not
as alert as day before. I know she is homesick. She is not good with
environment change. She was a stray that found me 5 years ago. I
brought her into my bedroom to seclude her from the other cats until
she got checked out. After she got a clean bill of health, I
encouraged her to roam the house freely but in 5 years she rarely came
out of my bedroom on her own. Occasionly she would come into my other
room if i was on the computer but she was happy just staying in her
little space. She had her own bed, water, food and a liter box in my
bedroom. I think I may bring her bed to the vets to remind her of
home. I am just praying she doesn't lose her will to live being stuck
in a cage with noisy animals and strangers around her.
