well to interject and return to the main subject,
1. yes lessoning the feeding will result in a smaller or slower growth rate .
BUT!!!! it also results in more health problems,and a shortened life span.
if you truly want a healthy caiman you feed it to the very best of your ability.
if you wish to have a smaller caiman and still have it healthy you should look into finding a good home for it and look for a smaller breed of caiman like one of the two dwarf species.
Your pets health should be your main concern no matter what.
believe me you can gain alot of pride in yourself when you know your caiman is happy,healthy,strong and active, And you know its that way because youve made the effort to be the best keeper you can be for your pet,(and if looked after properly) your life time companion.
