re: Is diabetes in cats a death sentence if untreated for a little while?

I inherited my mom's cat when she passed away, and the cat was overweight. And before I could get the cat's weight down I noticed it peeing a lot more than it should. I took it to the vet, and sure enough it had diabetes. If it was my cat I would've given the cat it's last shot, but since it was my recently passed mom's cat I ended up having to give that cat insulin shots every day and it's not cheap.

But it sounds like your cat does have diabetes, especially if you are noticing it is peeing more than is normal. Take it to the vet for crying sake. And if the cat has already got diabetes, it needs to be seen by a vet. Again, either take the cat to the vet or give it it's last shot, but don't wait, geez.
