Thank you for your suggestions.
I have upped her steroid because she lost more weight as of Mondays vet visit.
I have completly eliminated chicken from her life as of 4 days ago.
I have read about an introductory diet suggested on feline-nutrition.org of meat broth. I think I will give that a try. I will also re-introduce probiotics at a much slower rate. I think I caused the problem with them because i didn't realize they had to be introduced very slowly. I have a human one or I may buy one suggested on that site.
I am not giving up. I know the answer is out there. As long as she is happy and enjoying her life I will keep trying and trying and trying.
