Hi Elizabeth, so sorry you've joined based on these circumstances, but welcome. Clearly you've done a great job with your boy to be here in his 8th year with diabetes. But
@FurBabiesMama is correct, while there are plenty of suggestions on how to gauge quality of life in general, I presume that you came here because you are more concerned specifically about your kitty's diabetes, and all of the questions she asked are exactly what I would ask. A few others would be things like: are there any other health issues, like are you seeing diabetic neuropathy (walking "flat footed" or down on his wrists), and more general questions like does he eat well or is getting sufficient food in on a daily basis a real chore, and what do you feel his quality of life is?
So we encourage you to post over in Feline Health to get more eyes on your questions and answers to some of these new questions, and we'll go from there.
That aside, our boy Whispy has been with us for a little over 4 years now, and we know that he was diabetic for 3 years before that (which is why he was turned into a shelter 7 years ago, because he was diagnosed diabetic). So we are just now entering his 8th year with diabetes as well, and he is doing very well on the whole. Knock on wood, we've never had pancreatitis, and never had DKA, so that certainly helps. Whispy is clearly getting to be an old man, we estimate he is 14-18 years old now. I say all of this only for you to know that it is absolutely possible for these guys to live with diabetes AND a good quality of life for a very long time. But "Each cat is different" is a popular saying here, and it couldn't be more true than with regards to longevity with diabetes. So that's why we want to dive in and explore everything about your boy so that we can see if there are other suggestions we can make to help.
Hang in there, you are among people who care, and who "get it".
