When I was reading the other posts on post hypophysectomy meds, sounds like there was some desmopressin dose tweaking going on. One member even bought her own refractometer.
Sorry Eddie has to go back in for another poke for urine. My vet would get enough she could run extra tests if needed. But cat's don't always cooperate with that! It has to be taken by cysto. Neko once went if for a cysto to run another UPCR and as they were getting her ready to poke she flooded the exam table.

They scooped up some of the expressed liquid and the UPCR was way higher than normal, so kind of a waste. And you've already heard us say trace protein is no reason for a UPCR yet.
