Thanks to all who wrote me concerning my friend's ferret that had blood in his urine and had been straining after urination. My vet did an exploratory today. She said his bladder walls are very thick and stay disdended even after urination, giving him the sensation of a full bladder, hence the continued straining. She sent a tissue sample off to Dr. Williams. She said it looked like scar tissue or some type of fibrosis. Unfortunately, she didn't think there was anything that could be done for him. He is on pred and hopefully, that will ease his discomfort. Right now he is eating and playing normally and seems to be a happy little boy. My friend will sadly have to make a call if the pred does not help and his quality of life dwindles. I will post again when the biopsy results come back.
