Maybe he did pass a stone... he's not been showing crystals in his urine, but the vet said that doesn't mean there are no stones. Would the x-rays detect stones? I wish I knew if he had stones, because then I'd probably want to be changing is diet? I still haven't seen any blood in his urine (nothing obvious, it isn't even brown). strange... last time this happened it took several days for the blood to go away. He also wasn't sick that time (not vomiting).
He's doing pretty good today, thanks for asking... seems almost back to normal. He is still a bit tired, but we went for a walk and he wasn't sluggish at all. He's been eating his canned bland diet and asking for more, which I'll give him in a bit.
