This is my first post, but I'm in desperate need of advice. If this would be better suited for a different part of the forum, let me know. I'll try to keep it concise. Below is an overview of everything so far, followed by our current issue. Zephyr, my 12 yr old, 15 lb Tabby, was diagnosed a month ago after a routine check up. Other that frequent urination, he had shown no symptoms leading up to this. BG was in the 400s. It was the next week before the vet could get me in to show me how to give him Prozinc injections (1 unit) and to give me Prescription Diet w/d (which I have NOT given him thanks to this forum). I waited until the weekend to begin injections because I wanted to be around the first couple of days in case of hypoglycemia (my wife and I both work full time). Per my wife's urging, I did more research to make sure we understood the treatment. I came across catinfo.org which led me here. Thanks to catinfo and you wonderful people, I went out that same day and bought a week's worth of Fancy Feast (Classic only) and made the switch cold turkey since I hadn't begun injections yet. For 2 weeks Zephyr and Bailey (12yo siamese) loved the new food. Bailey still does, but over the last 2 weeks Zephyr has become less and less interested and just wanted his dry food. I've tried lots of "tricks" to get him to eat the canned and to keep his calorie intake at 100 at least, more if I can get him to eat enough (vet said to try to get him to 12 lbs, 10 lbs ideally, so I guess 150-200 calories would be best based on what I've read here). I've tried: -sprinkling his science diet on top -crushing science diet to powder and sprinkling it. -switched to Wellness canned, he ate it for one day -got Evo cat and kitten DRY to feed him and try the above tricks, he liked this food for a few days. Each method has worked for a day or two and then I have to try something else. I often have to relent and give him dry food only (now EVO, 8% carbs right?) and/or some tuna just to make sure he reaches his calorie mark. THE ISSUE NOW: Zephyr doesn't seem to care much for eating at all the last few days - wet, EVO dry, or his science diet from before. He's not necessarily lethargic, he's alert, he purrs but he is laying around more. The only thing he's enthusiastic about is these Get Naked Urinary Tract treats we bought on a whim http://www.amazon.com/Get-Naked-Urinary-Health-Crunchy/dp/B0076Y29AW which he gets really excited for, so I don't know if it's an appetite issue or stubbornness. I'm ashamed of this, but I have not begun injections yet. At first I was fearful because of the food switch, having read the amount of insulin required will drop immediately after switching, and not knowing how much to give him. I think I've been hopeful that the food switch alone would take him into remission, which was naive of me. Now I CAN'T inject him because he won't eat a full meal. I'm also ashamed that I was only giving them a half can of Fancy Feast each twice a day at first (3oz each per cat per day). It seemed like so much food, but then I did calorie research and realized I was only giving them half what they need. I tested him for the first time this morning: 394 without eating : ( Zephyr's shoulders, back and hips have been getting bony ever since the food switch, I don't know if this is good or bad. I'm starting to get really scared. This is specially scary because he was always happy and eager to eat before daignosis, so this disinterest has developed over a month period. I'm ready to stop being fearful and begin injections, but now I have to get him to eat to do so. Any advice would be greatly appreciated. This is an incredible forum, and I thank you all for providing such a crucial resource.
