Nothing but good news from Whitey's ultrasound. No large stones. No sand grains. Some mucus and thickening of the bladder wall, both of which are consistent with an infection. He needs to go back for a urine sample in a week, but it looks like we'll get out of this without serious problems. Yay!
Whitey says his stomach is cold, as they had to shave his nice luxurious tummy fur. I reminded him that it will grow back.
