Hi slick and welcome to Pet Talk. This is a wonderful community and I think you'll enjoy it here.

I recently posted a topic similar to this one, so you may want to look at some of the reader's responses here.

Choices like these can be hard. I would suggest you think about how your cat is now, how she looks, acts, what her quality of life is etc. My mom and I decided to start treatment with our cat Socks. His quality of life is still good, he seems ok aside from the fact he has diabetes and he's on a special diet right now...due to go in for re-testing in 2 weeks.
If you take Speckles into the vet for the bloodtests, and it looks like it's at the very beginning stages of diabetes, you probably could try food treatment, which is what we're doing right now. He actually isn't taking injections just yet, because the food the vet has given us is helping. We recently took him in for the 2 week check-up to see if he needed to start the shots, and he was actually maintaining at 260, which still didn't require the shots...which is why we have another check-up in another 2 weeks.

If it comes down to giving shots, we will probably opt to do it simply because Socks is fine otherwise and he's pretty tolerant of stuff like that.
Really, the main thing is to take a look at your cat and think about how her quality of life is now, along with the suggestions your vet may give. This is a tough one, and my mom and I were so upset when we found out about it, but at least it can be treated.
**hugs** to you and dear Speckles and do let us know how she is and what you decide. All of us at PT are here for you and feel free to PM me or post here if you have any other questions or concerns. Looks like you and I are in a similar situation.
**hugs**
