Thank you for all the prayers and candles for Sam!!! He did urinate last evening at 855p. I did not have to give him the IM Valium(though I was a wreck until he did void, I thought about using the Valium(ONLY kidding)). Sam, since the day he was rescued last March, has been eating Royal Canin SO canned. NO DRY FOOD at all....We will continue to watch him closely.....and again, thanks for the prayers!!! I KNOW they did the trick!!! Sandra
