Thanks for the help. As you can see, Leo started behaving today with a nice blue AMPS. Just as I'm getting wrung out completely, things are looking better. His nadir at +5 was 74; PMPS back to blue,so curious to see where this goes. When he was not eating well several days ago, back to tuna water and baby food. Thank goodness the not eating was not as bad as earlier this year and he was onto the pate quickly.
Before he had this last issue (and did the lip smacking you previously asked me about), I tried the EZC sample with chicken, and he gobbled it up and loved it, so ordered more EZC. They are accustomed to raw, so I was thrilled Leo liked it. I so wish Leo could be like Rain's Little Man and get off the juice! After the shorter duration of not eating well, he won't touch the EZC. What's strange is that our other kitty wouldn't eat the trial sample, but will eat the new supply.
I still give the usual LC, but do add a little 10% more frequently than ever to increase the carb %.
What is your thinking about using the higher LC %? I know how I feel when I stay low carb (<50 gr)! I used to go even lower at 25g.

In fact, I don't do that anymore.
I keep looking for a higher LC %, but everytime I start looking through the database from and then check Chewy, and find they don't have it.... back and forth... end up having to do other things around here, I never get back to finding what is available. Maybe I need to make another post in another area of the forum and query for other Sugar Moms & Dad's for what they use.
As far as the vet, last time I went to the vet for labs when he first started having a problem, the results didn't show anything. The second set of labs was 12/19/23; his annual was 10/28/23. After the 12/19, lab results, I brought up the other test you suggested for pancreatitis, and she said sure, anytime you want. With the many times of not eating, I haven't been too keen on the test because he has to go so long without food. What a crazy lab. He's lost so much weight.
