It will if he is bouncing. He had a yellow this morning. Maybe he had a blue or green low last night. Its likely looking at these numbers. And if he did go low then his body may overreact in a bounce (definition below). If it is a bounce he could continue the pinks and yellows all day. And that tells us a lot!! ( including the fact you might want to get a night time test to see how low exactly he is going)
I think the insulin is fine. Lets get a +6 and a +9 and a before bed test at say PMPS+3. If its a bounce he will stay high for while then come down. We want to see that trend.. and catch the low.
Thats why we ask for mid cycle tests -because if he is going low, it could be dangerously low.
a bounce:
Bounces - what are they and is my cat doing them?
When a cat is first diagnosed, the blood glucose has probably been high for a while. As the insulin starts to take effect and numbers start to come down, the liver has to learn to adjust to the lower numbers. We call this "liver training school". But before it relearns that low numbers are ok, when the BG drops to a number lower than the liver is accustomed, or if BGs drop low, or if the BG drops suddenly, the liver”panics” and reacts by releasing counterregulatory hormones and glucagon. This drives the BG back up. This is what we call a "bounce". Bounces can take up to 72 hours to clear so we are generally careful about increasing doses during the bounce. Once the bounce clears, then you can see the "real" numbers and determine if the dose needs to go up or down.
