My cat is currently on 3.5 units of insulin administered once daily at 6am. We are using Vetsulin. Do you consider this a high or average dosage for a cat? He is 10 pounds, 13 years old. He was diagnosed with diabetes 6 months ago, we updated his dosage in December from 2.5 units. Since the diagnosis my cat is always hungry/looking for food and his behavior has become very strange. I caught him chewing on the sponge in my sink on a few occasions. I understand the reason why he feels constantly hungry. I just want to provide him with whatever comfort and support I can. Has anyone else dealt with similar behaviors? Should I speak to his vet about increasing insulin or would a different adjustment help him? He is on a wet food diet. Thank you.
