Hello! First time post here and have already gotten so much out of this forum! I have an 8 year old male domestic short hair cat, Mr. Binx. He weights 15 lbs now, but was 24 lbs just 5-6 moths ago. The weight loss and increased awater consumption led us to taking him in and He was diagnosed 6-7 weeks ago with diabetes. Since then, he has been on Purina DM dry food. And, we have been gradually increasing his insulin, slowly. We started at 2u, and his numbers were still over 600. He's current dosing for the past 2 weeks has been 5u twice a day (12 hours apart). We have been giving him insulin right after feeding him. Accoridng to the Vet, His blood work all looks good. He's ketone levels are good and no UTI. She thinks he may have a insulin resistance. We did a glucose curve today and looked like this: 7 am: feeding and insulin 8:52 am: 572 9:38 am: 467 11:37 am: 524 3:23 pm: 579 5:23 pm: 428 We'll be feeding him at 6:30 pm and giving him insulin again at 7 pm. He is having accidents and drinking lots of water still, but otherwise happy and acting normal. Our vet has written a script for Prozinc, but I'm not confident it will work. We are going to switch to wet food starting tomorrow. We greatly appreciate any additional guidance or advice on how we can get his #'s down to within range. Should we increase more then 5u?? switch to Prozinc? Hospitalize him for 24-48 hours? Thank you!
