Grady has never shown any signs of not feeling well - despite the frequency and hematuria.

We segregated him last night and everyone survived. He is peeing, and there were two decent wet spots in the box this morning.

Stress - yes, she mentioned that as a cause. He really doesn't have much in his life; but Charley does pick on him from time to time. I tend to attribute all his problems to in-breeding. We strongly suspect that his father was also his older brother. Grady was 'rescued' from a house up the street when he was 6 months old. They never even missed him.

Candace - thanks for all the suggestions. I most certainly will bring them up with the Vet.

Thanks to all of you for your concern and well wishes. We all appreciate them.
