I went to the vet this afternoon and had an hour consult with the vet. He's really awesome. Tilly will be on 1 unit of insulin 2 times a day. She also really likes the new food that the vet wants her on. Luckily I can feed both Tilly and Nutmeg the same food. Nutmeg didn't eat all her serving though, which may be an issue because Nutmeg really misbehaves when she's hungry. I'm hoping that when she realizes that when she doesn't eat it she can't go back to it she will eat all her food at one time, but time will tell. So we are managing for the moment, and I'm trying not to be totally overwhelmed and stressed about it all. Thanks for all your prayers.
