Hi Carla!! I'm on the west coast and will probably be hitting the hay here shortly since you seem to be okay right now. I know you had a scary night!! I see you were giving Boo dry food along with karo tonight. Does Boo only eat dry or does she eat wet food also? I don't know what info you've already been given, but just a couple things...when your cat's BG is tested in a vets office, the numbers will very likely be elevated, sometimes extremely elevated, due to stress. When a vet is escalating the dose of insulin based on numbers taken in their office, there's the real possibility you will be giving your cat too much insulin. Unfortunately, you found that out the hard way!! I know that because Boo went below 50, she earned an automatic dose decreased, but because the dose is already too high, I don't know what dose the experts here will tell you to go with. My vet started Champ on 3u twice a day. I did that for 12 days until I found this site, and I immediately dropped his dose to 1u twice a day and started from there. It didn't do Champ any harm, but I'm not so sure it did him any good to do it that way. Again, the experts here will be able to advise you in the morning. You really must try to get Boo off dry food, though, and stick to a strictly low carb wet food (Fancy Feast classic varieties are a favorite around here). It may be that Boo won't need much insulin, if any, if you can get her off the dry food. If you have time tonight, try to read all the stickies at the top of our forum. It will give you a lot of information about Lantus and how it works, and how the protocol works. If you have any questions, there are a ton of people here who will be glad to answer and help you out with Boo. We are a very close knit family here. This forum and the people on it have saved my sanity!!
