Hello my cat Mercedes was diagnosed with diabetes back in January. He is a 15 year old male domestic long haired cat who I had since a kitten. I never had any health issues with him until around christmas time. He started urinating outside his litter box, large amounts, bloated stomach, and he was acting very strange. I took him to the vet and after X-rays and blood work I was told his bg was over 600 and he needed to be on novolin N. He also had a blockage so I was given lactulose to give him twice a day. He is an indoor cat who had ate the same food, Iams dry for about 14 years. The vet suggested I did not change his diet because of his age and high protein in the other foods? Anyway, I started the novolin N and bg's were still very high. The vet suggested he spend the day there and they monitor him every 2 hours but nothing had changed. Every few days I would take him back for a bg and was told to keep increasing and he was possibly insulin resistant or had some rare disease? I decided to google and Google my days away and took it upon myself and with the help of other members to change his food to fancy feast classic. I also took it upon myslef to stop the insulin since I was worried giving 6 Units twice a day and no progress. About a week after the new food and no insulin his sugars are in the high 200's low 300's. He weighs about 13 pounds and was always a heavier cat since being neutered. I have now taken the advice of fellow members to start him on lantus which will begin in the morning. I am not sure if I should being with the lowesr dosage or 1 unit twice a day? I have met some wonderful people who are helping me a great deal and I feel very comfortable with starting the lantus! Some have made comments I should of never stopped the Novolin N but it wasn't doing anything I feel. I feel like besides finding out my cat was diabetic and had a blockage my vet is kind of useless. I called the other day explaining I took him off the insulin and changed the food and the vet was like "wow his numbers went down, that's bizzare?" Anyway he gave me a prescription for the lantus pen and a very very kind woman was able to help me get it. So I am ready to get the ball rolling in the am and get my baby back in shape. I have also started him on Zobaline because his legs seem to be weak. Thank you all for listening and I appreciate all the input I can get.
