My ig was 33 in at 2 yrs old.. he was always a small iguana.. he just passed away Monday at the age of 22 and was around 47 in long. Just an FYI don't feed your ig kale on a regular basis. they cannot eat anything from the brassica family which includes kale, cabbage, cauliflower, broccoli, bok choy or chinese cabbage. I never fed my ig tomatoes either. I read somewhere that they can't eat them either.
