If you were a vet with a patient that has a history of crystals, and an Xray showing a possible stone, don't you think if he didn't pee allll day that you'd worry that he would block completely overnight? Wouldn't you take precautons to protect that patient?
Oh Kim, why don't they help him???

I'm no vet of course, but it looks to me like he's definitely blocked! At least they should take another x-ray to see if the bladder is full!!
