I have just joined the group with Boots who was diagnosed with diabetes in February. So far we have had no luck stabilizing his BG. He is currently up to 5 units twice a day. I feed him 1 cup of Royal Canin Diabetic DS with 2 spoonsfull of tuna and water mixed in twice a day at 7:30 am and pm, then I give him the insulin, lantis glargine, about 20-30 minutes afterwards. The vet said we would look into something else if the 5 doesn't work (it's not) for him, the appointment was last Tuesday. This is my first experience with feline diabetes and at first I thought it was a death sentence until I read about it on the internet. I'm hoping to find out even more information on this site about how to proceed and how to do the very best I can for him. How high of a dosage is it possible to go up to? What else is the vet referring to? On Tuesday at 2 pm his reading was 320, is that horrible? The vet checks him every 7-10 days. Here is the story about how Boots came to live with us. He was inspecting homes in the neighborhood starting in January. He would peer into the cat window next to my front door (I started to fall in love with that little face then) or sit on the back patio and look in the sliding glass doors at the rest of the cats that live here, there are 17 others. They must have given him a good report because he chose us!. At first I thought he was a neighbors cat but one day found him sleeping in a cat nest in the vacant lot next door. So I started feeding him and finally was able to pet him by the beginning of February. On Feb. 9 he got in a fight with a raccoon, was bloody, beat up and had many puncture wounds, I came home to find him waiting by the front door. I brought him to the vet, and while he was there had him neutered. I waited and waited for him to recover, the wounds healed, he lost a lot of weight, started urinating so much, and he just wasn't right. One day, about 10 days later, he had bloody stool and looked really weak so back he went to the vet and I was sure he was a goner for the second time. That's when I found out about the diabetes and have been struggling since then to get him well. He is the sweetest cat and is so happy here. He hangs out on one side of the house with Baby Girl who pretty much doesn't get along with the rest of the crew. He took to sleeping on the bed fast. So I don't know how old he is, how long he's been sick, nothing at all except he's a very special guy and is loved very much. Is it normal to take so long to regulate the insulin? Any ideas and suggestions are welcome. Thanks for reading.
