I’ve had two (at same time) on insulin shots years ago. They only lived a couple years on it. They were younger too (12 and 13).
I have Whitey on just a small dose. Not taking him back for a curve or anything, I just raised it a small fraction snd he seems to be doing well. They found what they thought was a tumor in his lung the last time he was in in February. They took xrays cause he had breathing issues. But I’m thinking they were wrong. So far he’s doing much better. Breathing better and put on a little weight. He was so thin before. So we’ll see.
He’s feeling much better which I’m happy about ,
