Seeing that blue makes me wonder what's happening during the middle of the cycle. For some cats that are started on a high dose of insulin, it can kick their pancreas into gear. It's like a jump start. Those red numbers could be bounces from lower numbers. Since it's the weekend, would it be possible for you to get more mid-cycle tests, especially during the PM cycle so you can tell if, in fact, Teronto is seeing more blues than you've been able to catch?
