The insulin will help no matter what Calloway is eating. I cat sit for a diabetic kitty. His "mom", who is in her 80s and is like talking to a brick wall sometimes, won't regulate his food or change it from Nine Lives so something higher in protein. He's doing well on his 4 units twice a day. Even though it makes me so mad, I am happy that she will at least buy him the insulin. Also, with the shots, the more nervous you are, the more Calloway will be nervous. So I like what you said you did about just rubbing him when giving him the insulin. Just make it an enjoyable experience and he won't notice. After a few more days, you won't notice either! Glad that there is something Calloway will eat!
