That's what
your Vet told you for Chloe. It doesn't apply to everyone else's kitty. Mufasa does not react the same way Chloe might. There's no reason to get defensive on another's thread.
Jenny, have you ever tried pure pumpkin for Mufasa? The added fiber can help get things moving as well

. I can give you more specifics if you're interested. Since you're at work during the day, I would say skip the shot if you get BG less than 150 until you can see how low the decreased dose takes him. Looks like that 2.0U dose was his breakthrough dose and he's on a mission now

.
If for some reason he does bounce in the morning to like >300, do NOT raise the dose. Numbers permitting (BG over 150) I might suggest trying 1.25U
