Hi all. This is all very new to me and I've read through a lot of threads and there is so much knowledge here I hope you can help. I have a lot of questions. My cat Comet is 11 years old and was newly diagnosed. He had all the signs. Drinking and peeing A LOT, and weakness in his hind legs. His numbers were in the 500s and was put on 1 unit of Vetsulin twice a day. After 10 days his numbers were still in the 500s so the Vet increased the insulin to 2 units. Now here's the thing, he is stressed, as am I, when he goes to the Vet so I don't know how accurate the numbers are. I know testing at home is best but what should I buy? Also after the 10 days with the 1 unit he is absolutely drinking and peeing less but his legs are worse. I've also read that food high in carbs is no good for a diabetic cat but he's on prescription C/D for the past 3 years, post PU surgery, which is very high in carbs. Prior to needing surgery I had him on Purina Pro Plan for urinary and he did fine with that for a number of years until I got a second cat. They get along great but I think at the time stressed him and he developed crystals again. My question on that is the C/D doing more harm than good? Next is his legs. I'm so worried they won't get better. I've seen B12 shots mentioned to help with that. Anyone have any more info on that?
