Dear Di. Your girl, Lisa, will not be in remission by August 20th. It takes a two week trial, without insulin, in order to officially reach remission and she is not ready for the trial based on her numbers and her dosage. I am hoping the good folks on this site can help you with your Lisa and also allow you to take a 10 day vacation. It would be a blessing if your Mom could learn to test. It is always risky to give insulin without the test beforehand. And, at least a test or two, during the cycle is recommended. Can you teach your Mom to test? I know it is hard in the beginning but kitties learn to get used to it - and so do caregivers.
I want you to have your 10 day vacation but I also worry about Lisa. If you could put your vacation off for a couple of months, the folks on this site might help you get her into remission so she could be safe and you could enjoy your time away without worrying about her. I know that is asking a lot of you but please consider it.
