Hello friends, my 11 year old Devon was newly diagnosed by her vet as "mildly diabetic" in late July this year. It was a fairly rapid loss in her weight within a month or so, drinking water a little more frequently than normal and lethargy that alerted me that something else was going on and it wasn't just the hot humid weather at the time in southern Ontario. The vet prescribed injections of Lantus 1 unit, 2 times/day, as well as 1/2 can twice a day of "Purina DM" (dietetic management). She really liked the food to the extent I wondered if there were flavor enhancers in it. By the end of August her glucose level was good (4.6) and she had gained half a pound and her insulin injections were reduced to 1/2 unit/day after her morning meal only. She was doing well, and I was hopeful she might achieve a "diabetic remission". Over a weekend I ran out of the Purina DM food and went back to her old food (Pet Valu's "Performatrin" Adult) mainly beef and turkey flavors, fish occasionally. In about a week's time I noticed a weight drop, and she was drinking a little more, with larger pee clumps, so I put her back on the Purina DM. It was 2 weeks since she had her glucose and weight checked today, and I was shocked that her glucose was up to 21.1 (higher than her original reading of 19.4!) and that her weight had dropped from 7.8 lbs. 2 wks ago to 6.9 lbs. today. About six mos. ago her weight had been a stable 9 lbs and she was never overweight. So the vet upped her insulin to 1/2 unit, 2x/day. The vet said that I should not have gone back to her old food (even tho there are no grains, or carbs like potatoes, cranberries or other fruit in it). The vet also said that even giving extra treats apart from the meal will cause the imbalance even tho I was giving her a couple of Pure Bites treats (freeze-dried chicken or liver) after her injection. I guess my question is: Purina DM is expen$ive (twice the price of her old food), but am now afraid to try anything else. Will my girl be stuck on eating this food for the rest of her life? I've been a cat owner for many, many years but this is the first diabetic cat I've ever had. I hope she can get a diabetic remission. Do you think this is possible?
