Our 10 year old cat Rocky was just diagnosed with Diabetes mellitus yesterday. The vet said he was in the advanced state, but we could try insulin shots. Glargine injects twice a day and diet food ( I've researched no need for expensive diet food Wet food only low carb high protein). He said to buy it from them the first time it was $300.00 a vial. He did say he would write a prescription so i could purchase it online . I havent really found a cheaper place to purchase it . Only a few dollars . How long does a vial usually last if he requires it twice a day? He said i could monitor him at home I would need to take him in quarterly for tests . He said there is debate rather a human meter is as effective as a pet one but i could use a human one. I found one at Walmart for around $10 and strips are about $20 for 100. How is it getting started? Do i check him every hour? Every day? What if its high or low? Anyones kitty ever go into remission ? He said he has seen 2 cats his whole career who where able to come off insulin. Also how are you kittys ? Do they take well to test and shots? Are they relatively happy healthy?
