I'm at a loss! My cat, Ezra was diagnosed with diabetes 5/09. He was on Lantus until 8/09. As his BGL went down, we weaned him from the insulin. His diet consisted of 7-9 oz of low carb FF over 4 feedings a day. I have continued to test Ezra even though he shows no symptoms of high BGL. His BGL had been between 50 & 130 until December. All of a sudden he had 3 days in the mid to high 200's. I reduced his food to 6oz of FF a day. His BGL dropped again but not to the original levels. Now his levels range between 110 & 170 most of the time. About every 2 weeks or so, he will jump into the 200 or higher range. Example: On Tues 113, Wed 230, Thurs 213. I haven't tested him yet today. He shows absolutely no symptoms. He is active, doesn't drink much, nor is there excessive urine in his litter box. Every so often I fax his readings to our Vet. She doesn't seem to concerned about his erratic levels at this point. She said if Ezra had consistent readings over 230, then we can discuss starting insulin again. Any suggestions out there?
