good morning, debbie. it's 5:30 in the morning and i woke up thinking about Lucian. I hope he's hanging in there this morning. what he needs now is food, water and enough insulin.
Do you know the tricks for getting a cat to eat? With him flirting with ketones, it's critical that he eat whatever he will. even if it's med or higher carb, he needs food. you can finger feed him to try to "prime the pump." heat it up, pour on tuna water, sprinkle some parmesan, oregano or catnip on top. pulverize some dry if he's a dry food addict and sprinkle it on top.
also, water helps flush out ketones. if he will eat food soupy, add as much water as he will tolerate. if he eats and gets some water in him, he'll feel better.
please update if you are able. i'm going back to bed but will look again for your update later.
eta - i just looked back through a couple of days of your posts. Debbie, there are definitely other options to try to get him regulated besides stopping his insulin. i don't know what else you've tried. Have you tried tinkering with his food schedule? sometimes feeding at ps, +1, +2 and +3 can slow down the initial drops that can cause bouncing, thereby helping to reduce it. another option is to increase the carb content of his food to lift up his nadir (make it higher) to allow you to give more insulin and bring down the top numbers. I used R with punkin mostly as the cycle began to rise to prevent the high numbers from happening rather than after the bounce happened to try to pull them down.
and yes, absolutely, going without insulin can send him into DKA.
when i look at his ss, i don't see an unusually bouncy cat. honestly, it looks pretty typical. i don't normally even look at the Relaxed board but someone asked for help for you. i think we could help you get Lucian into better numbers.
