Please help. My cat, Emory, was accidently given a double dose of his insulin. There was miscommunication between my husband and I so the the shots were spaced by 30 minutes. We don't check his glucose levels every day but at last check the vet said it was around 320. He gets 2units of Lantus BID. I'm worried about hypoglycemia, and I'm not fully sure what symptoms to look for. Any help would be much appreciated.
