Hi. Mia's glucose numbers have been high the last few days. So, I have been checking everything I can. She does not have ketones. I use PrettyLitter when I have concerns to see if the urine changes the litter color indicating an issue. I put some out a few days ago, and it was yellow she went and when Willow went, so I stopped controlling access to the room where it is and was just letting them use it as they wish until it is ready to be thrown out. When I scooped it yesterday morning, there was blue/green litter. The litter info says if you see a color change once to monitor for 24 to 48 hours to see if it persists. I put out fresh PrettyLitter and begin controlling access again. When Mia has gone, it has been just slightly greenish (compared to Willow's that is just very yellow.) The litter info says yellow to a light 'olive green' is okay. So, supposedly, it is okay, but when I have used this to test in the past, it was always just yellow. So, I ordered PetConfirm Urine Collection Cat Litter and UTI test and had it shipped to me overnight. It came today, and I did a test. It shows positive for Leukocytes but negative for blood and Nitrites. When i started looking up info, it sounds like maybe the Leukocytes do not matter so much??? Her glucose numbers so far today look so much better... could she have had an issue that cleared up on it's own? Can someone who knows about this stuff PLEASE help me? I don't want to overreact, but I also do not want to ignore a warning sign. Should I call the vet's office and ask if I can take in a urine sample for them to test? Should I take her in? Should I wait and see, maybe test again in a day or two?
