WE got back the results. Thankfully no acromegaly, but he does have IAA. My vet takes care of a lot of diabetic cats, but has not see this much. Pumpkin is on 9 units of Lantus AM and 9 units PM right now. He is acting normal, not lethargic like before we started giving him insulin. He is even jumping and wrastling with my 4 yo cat. The vet says we should start slowly increasing him but his body will fight it off. Anyone else with a cat with just IAA have any advice? Does switching insulin help? Thanks!
