Welcome Dave & Tiger Lily to the FDMB Family.
You have now found the best place on the web that you never wanted to be. But also the best place to help you help Tiger Lily.
Couple of things folks will be asking so I'll get them out of the way early. Do you know yet what insulin Tiger Lily will be on? And what your starting dose will be? The motto here is start low and go slow.
Also what are you feeding her? We recommend, a low carb/high protein wet diet for not just diabetics but all kitties in general. So if you have more that Miss Tiger Lily you can give this diet to everyone.
Also the absolutely best thing you can do to help your little girl is learn to test her blood at home, and we can help you learn, we have taught hundreds of folks to do it over the web. It may seem pretty scary and overwhelming at first but please trust me it is absolutely the best thing you can do to keep her safe while she is on insulin. Think of it this way, you never see a human diabetic inject insulin without testing their blood first, so why do it to a kitty? It is actually very very easy once you get the hang of it. We use a basic human glucometer and strips that you can pick up at any drugstore. I personally use the Relion mini that I got from Wal-mart for my sugarcat, it is fairly cheap and so are the strips, plus most Wal-marts are open 24hrs so I can always run out to get supplies if I need them at midnight. When we test we take a very small sample of blood from the kitties ear. This doesn't hurt them at all, in fact my boy will purr through the whole process, some even sleep through it.
The other advantage of testing at home is two-fold, 1) you will get truer numbers than the vet because all kitties for the most part are under stress at the vet's and stress raises BG. Plus you will be saving $$$ doing your own curves. and 2) You will be able to see if her bg numbers are safe to give insulin, since the one thing you don't want to do is give insulin if her numbers are too low, as this can cause Hypo.
Home-testing very likely saved my boy Max's life. Since I adopted him from this board just a little over a month ago as a diabetic. If I hadn't been home testing I would not have known that a simple change in diet had sent him into remission. Because he went OTJ (off the juice/off insulin) in just a few days of being at home with me. Had I just gone ahead and shot his insulin that he had been started on I could have seriously hurt or killed him, because he was so new to me that I would not have caught little personality changes, or have blown them off figuring he was just unsure about his new home. So I can not stress hard enough how important testing is.
Only other thing I can think of right off hand is don't let the vet talk you into some of their pricey prescription foods, they are usually way over priced and there are cheaper and with better ingredients on the commercial market. I feed my guy either 9-lives or Friskies pate flavors.
I'm sure others will be along shortly with a ton of advice and links for you to read and study.
Welcome again!
