yeah im a little bit worried, mine is also over 4 feet long. but like everyone says, bites arent as painful as you would think, i have yet to be bit by my Ara, ive also only had her for about 4 days, i have not handled her much. i pulled her cave off of her and took a few pics, i had to move her out from the corner in order to place the cave back in its original spot. do not show fear. i think they can sense it!!! let me know if or when you get bit! i do not think you will tho
