Hi there! As I mentioned in my last post, Roo just had his dental with a couple of extractions a week ago today. The vet asked me to check his urine for glucose and ketones, so I ended up buying some of the hydrophobic litter sand and some pet urine test strips (since I think the Ketostix or ReliOn brand strips only test ketones). Based on trying three strips, I'm pretty confident that there's no ketones in the urine, as I'm not seeing a color change, but I'm not so sure about the glucose - its getting brown in some areas but staying blue/greenish in other areas - can I get a second opinion? Is it possible the brown spots are where the sand is being scooped up in the pipette?? Pictures attached, taken right at the 60 second mark indicated for both glucose and ketone tests, I've circled where I dripped the pee as I only tested those two. Help!
