kjc, thanks for all this info...most of this I've already read while doing research. You indeed are not "arguing the point" with me, I am all for whatever needs to be done to determine Rocco's problem. I've absolutely been monitoring his urine output since yesterday and he's definitely not retaining it...quite the contrary, poor little guy still has a few leaks due to the catheterization
. The biggest question is why he still has the urge even after emptying his bladder. The other major concern I'm having now is his stools, which I'm also awaiting test results for. I sure do have a lot going on right now, but as another poster mentioned, I have 3 sick kids - one is a furkid. And they all get equal care and attention...and Rocco is not getting anything by me - I'm faithfully monitoring his food and water intake, his sleeping habits, his mood, his bowel movements, and of course his urine output which is looking good since yesterday. Anything other than improvement earns him an immediate follow-up visit with the vet.
