Question: Hi! Our cat Scooter has been taking novolin for about 6 months. His numbers vary quite a bit even though we feed him at same time and give him his insulin at the same time. They range from 80 to 380 depending on the time of day. We are thinking of changing him to vetsulin but now that I see this I am wondering if it’s a good idea. This April 2016 though and I don’t see any recent posts. Would love an answer.
Thanks for writing in. Generally speaking, novolin and vetsulin are not recommended as the first line insulin choices in cats with diabetes. These insulins often have a short duration of action of blood sugar control in cats and control of clinical signs is often poor. The recommended insulins for cats are the longer acting glargine or protamine zinc insulin (PZI). I have included a link to the AAHA Diabetes Management Guidelines for Dogs and Cats for your review. I would recommend you speak to your veterinarian specifically about your cat and his needs. Good luck.
