My name is Jim, and my little buddy penguin was feeling a bit off and had lost a lot of weigh, and now after a vet visit has been tentatively diagnosed with diabetes. The vet is doing more thorough blood tests and plans to call tomorrow, but I’ve been freaking out since I started doing some research upon returning home. This forum looked like a good place to ask some questions, and hopefully ease my mind or help me know what our options are. A little backgroud on penguin, he was a stray when we got him, we don’t know his exact age (somewhere north of 8 1/2) or what if any vaccines he had had. He’s a happy, well adjusted little guy who until recently was a bit on the plump side. He is very picky on his food and getting him to eat wet is difficult on a good day. As far as the diagnosis goes, my concerns are as follows. First, obviously there is the cost of the insulin.
