Hello, I am new to the message board. I am writing because I currently work for a vet, and my cat, who was in remission for about 7 years, is diabetic again. I started him on 2 units of vetsulin twice daily this past Monday. I have noticed he hasn't been drinking as much water, therefore not urinating as much as he was prior to the diagnosis. However, he does still seem lethargic. I am going to test him tonight, before giving insulin, but I am thinking about asking my Dr. if we can switch him to Lantus. He was on Lantus previous to going into remission. Can I please get your input?
