I resued a male Himalayan in Feb 2011 who is about 4 years old. He has food allergies which I have addressed with the proper food, and has had stool & blood tests, but he still has chronic diarrhea. I started him on proviable dc which initially seems to have made it worse. He managed to jump over 2 stacked baby gates during the night and deposited numerous "piles" all over the carpeting in that room. Although he has diarrhea 24 hous a day it seems to be worse at night. He is a sweet animal and I would like to keep him but the diarrhea has to stop. Any suggestions?
