Hi Kathy,
Punkin was about 15ish when he passed away. We don't know his cause of death - it may have been cancer. It wasn't directly related to acromegaly or diabetes though. He was having weekly cold laser treatments for his arthritis to try to help him be comfortable. Somehow that laser caused bloody diarrhea one week. The vet was sure that it wasn't related. We went back the following week and it happened again after that laser treatment. He never recovered from that - his chest filled with fluid and it squished his lungs to slivers. Later I read that you shouldn't use cold laser on an animal that has cancer. As far as we knew, he didn't. But with a senior cat you can't really know. I realized that the angle of the laser when it went over his hips, then went down his spine, meant that the rays would've overlapped on his intestines inside. Perhaps it was just too much. We'll never know.
All that said, Punkin was treated with the SRT. He developed low thyroid from it, which we didn't discover for some time. The ordinary thyroid tests didn't show it until we specifically had them check for free T-4. He became anemic, too - and both of those things are very serious. He became a fairly fragile kitty, but his quality of life was still very good.
We had 2.5 years with him after he became diabetic. I don't know when the tumor started because I wasn't zeroed in on the topic at all before he was diagnosed. I'd never even heard of acromegaly. I put before and after pics of him in the thread on acromegaly (single topic links at the bottom of the New to the Group? sticky).
Here's a link to them. The changes happened so gradually that I would've said that his appearance hadn't changed, but from the pictures you can see he had.
He did have a good life and in spite of all he went through, I think until that last 3 days his quality of life was good. He was an extraordinary cat and if there'd been anything more I could've done to help him, I would've.
The best thing you can do for TiTi's dose is to let the tests tell you what to do. After 6 cycles, if you don't see green, you can increase. I would probably increase her dose in the morning if she were mine. If she does have acro, her dose needs may regularly change so you don't want to get attached to a dose. Just follow her lead.
I totally understand your worry about her - step back and think if you didn't know all the details of her blood sugar, would you think she has a pretty good life? If so, all is well. You can only do what you can do. I think you're doing an outstanding job of caring for her.
