Hi Marcy,
My name is Patti and I was asked by nancy to come take a look at your Klinger. My Merlin was an earlier kitty with acromegaly and used PZI idexx (no longer around but similar to prozinc).
REading thru your post some red flags went up for me. Merlin was diagnosed in 2006 and I've been involved with helping get acro more recognized since then. some of my concerns for your kitty are:
He's a big cat
He's male
He has a pot belly
incredibly hungry all the time
he has wonky numbers - one minute hi - next minute low - on similar doses - for no reason - this is soooooo typical of an acro cat on a pzi type insulin. It's one of the telltale signs we found on these kitties. It's not your meter! It's NOT rebound and you can test a million times - it's NOT rebound. I repeat that as us original acromoms went thru that a million times and that is what we fight against - the constant retesting for rebound!
Acrocats do NOT have to be on incredibly HUGE doses of insulin. You have already been up to 6 units bid tho and that is high enough. And the above symptoms/notes play into this too. We have been keeping notes/track of acro issues now more closely since 2006 and have more documentation. Your vet has probably never seen an acrocat and is only going by what she has read/learned. Please I mean no disrespect here. It's just what we've all learned in our experience of caring for our own kitty.
Just from what you've been going thru - I would strongly suggest you might want to get an IGF1 and IAA blood test drawn. It may give you peace of mind to find out what is happening and allow you to dose without second guessing yourself about the doses.
The Acro sticky has all the links for the blood tests for your vet. We also have the catacro site with even more info. Again - here are the links:

please let us know how us hi dose moms can help - we've all been thru a similar story to yours. IF you have any questions to what we are suggesting let us know. Nancy, myself and some of the others will check back in or c'mon over to the acro/iaa/cushings group too - we'll be watching for you too.
