I thought my kitty had developed it when I noticed he was drinking bowls full of water and then peeing forever and ever. I took him to the vet convinced he was diabetic. I, too, am diabetic so I rcongnized the symptoms. What he had instead was kidney disease! What's funny is a few years later I started drinking glasses full of water, etc. even though my sugars were relatively under control. My next check up - guess what? I had kidney disease!

I've always been curious, since cats eat little carbohydrate, what kind of insulin do they get? U, N, L?
