Hey Jade. My cat just got diagnosed on Friday, and I know how overwhelmed you're feeling... all too well.
One thing that's missing from your post is what symptoms your cat was having and what his quality of life is like. If he's in really bad shape, maybe putting him down is the humane option, but I didn't get that impression from your posts. Please let us know what his symptoms are like.
Unless he's in really bad health, I think you should at least try switching your cat to wet, low-carb food before you think about putting him down. What I've read around here, the low-carb food can make a huge difference, and if that's enough to improve his health then that's easy. There's a big list of all the canned food that's low-carb; I just went with Friskie's because it's cheap and available everywhere. Here's
a link to the shopping list of low-carb foods, but normal humans probably only need the Fancy Feast and Friskies section (pasted in below).
I'm trying home testing and it's a lot of time and work. It's very satisfying when it works, and it's frustrating when it doesn't. But to spend 20 minutes two times a day to *maybe* get one reading? And supposed to do that 4 or 8 times a day? AND keep the same schedule every day? That's not realistic for someone who works. Hopefully a better diet, occasional readings and some insulin (or not) will be enough to help my cat out.
If money's tight, you might talk with your vet about trying the low-carb diet before starting insulin. Insulin ain't cheap, and there's a some expense and hassle that comes with it. I spent 90 on insulin, 10 on needles, 15 on glucose monitor, 10 on testing strips, 5 on lancets. It adds up, and then takes an hour or more a day. But they say it gets quicker and easier, so I'm trying it out for a while. But if the food works pretty well for my cat, you can bet that BG monitor is going in a drawer (and would eventually be donated to someone else on this board).
It's just balancing what you're investing (time and money), and what your cat's quality of life is. Only you can know that balance.
I work for a nursing company that does home health and hospice care (in the office, not as a nurse), but one thing you realize in that industry is that everyone and everything dies eventually.
The question isn't whether you die, it's how you live. I think you do what you can - financially and emotionally - see what kind of quality of life your cat has, ask yourself, "Would I be okay living like that?", and then make decisions. If he's doing generally well but has occasional problems, maybe he's ok for now. If he's constantly sick or miserable, maybe not. Only you can know.
But I think you at least try changing the food first since that's cheap and low-effort, and has a reasonable chance of showing some improvement.
