A question about ketones. We bought the FreeStyle Optium blood ketone device. Is this device fairly accurate with Messuring cat ketone levels? Also has anyone else had their cat up at a higher level like willow was today at 3.7 but wasn’t showing any clinical signs there was anything wrong. I checked her as her BGs had been too high for several days. I did take her to the vet and she had fluids and fast acting insulin to help her levels go down. She was much lower at 0.3 ketones and 8.8 BGs tonight.
