Vet says to stop all insulin and see where she goes. I am monitoring food intake very carefully.
On the subject of vets: Sometimes I feel really bad for them. Veterinary services are not yet as good as our human ones. Instead of a general practitioner and many specialists, most pet owners have to deal with a single guy. And it's absolutely possible to treat a large patient load, and learn everything the vet school either didn't teach you, or to learn all the new information being learned, at the same time.
A typical vet is only one person, yet we expect them to know everything and keep up to date. It's not like you see on the new tv reality show, Vet School, which is a large teaching hospital here in Corning, NY. (Which is about 100 miles from us, btw). There are no speciailsts here in the boondocks...they're in the human hubs...cities.
So the average patient has to depend on one overworked guy who may have gone to school 20 years ago, and must now be godlike, and know everything. He's trying to keep up but especially if he has a family, it's hard to maintain a practice without burning out.
My own take is that's the reason vets depend on the pharmaceutical companies to do their research for them...and those companies have a vested interest in promoting themselves and their products. Painful fact, but true. Not everyone is a good guy, and the bad guys are sprinkled everywhere...the ones who look at their bottom line first, and patient welfare second. The pet food industry is a massive moneymaker, for the most part owned by only a few companies. They have lobbys in Washington and here in the USA, go in the back door to give out favors, and wield sticks against politicians who would see better, more reliable laws concerning the quality of goods in food production for both human and pet consumption, and drugs.
And these same manufacturers can make or break a vet's reputation.

They can give him a hard time if he speaks out against food quality. They threaten litigation if a vet doesn't go along with their outlines as to the worthiness of their pet quality foods. This happens with human products too. It's firm unyielding pressure that can take a person's livelihood away in a heartbeat. Perhaps most vets prefer to keep quiet, and be able to make comments privately, rather than fight the machine. Heck, without that mindset we might not even have many vets..
My vet is a nice guy, but overworked.

Like I mentioned, he is rural so he has a large patient load spread out over a huge area. He and three other vets in towns that cover a radius of about 80 miles, must handle everything. Half of the other vets do large animal work too, and that means travel time added into their daily time frame. This vet we have, is small animal oriented, specializing in dogs and cats only, so he's in big demand, and since this area used to be factory oriented, it's now a depressed area, with many people on fixed incomes or public assistance. He is very cost conscious, very sensitive to the human conditions within his practice area, and afraid to promote expensive protocols out to many of his patients, because it distresses them so, to not be able to afford the latest care. I'm sure it distresses him greatly to watch their pain.
Just like human emergency rooms everywhere...the personnel are subject to burnout.

So much emotion, and for most, not even insurance to help out...that's painful.
I think that's why our vet insisted we start with urine tests. He wasn't sure we could afford the initial diabetes protocol. Maybe he was trying to ease us into care without giving us sticker shock.
What he doesn't know about is, is that we have built up an emergency fund for the cats only. We have always kept multiple kitties, and to have only two now, is quite unusual. So we learned the hard way that if you don't plan for pet emergencies, it can be a lethal consequence for furkids.
We're stretched tight, but as long as our house doesn't catch fire, or we have a flood, or aliens attack

...we're doing ok. And now we have a group of diabetic cat owners online, who frankly have more experience actually fighting in the trenches, years of dealing with their own pets, than many vets will ever see. I am so glad we found you.
