I do think alex was cared for as far as feeding, and cleaning. But I wonder if he was just overworked, stressed and some sort of abuse. Such as, the article said he was worked 8 to 12 hours a day, he was struck on the beak with the object repeatedly until he gave the answer to the questions and the object was forced close to his eyes, was he blind? and surely his beak was sore after being struck on it for hours a day, for not communicating like they wanted him too? and also, where were his red tail feathers in some of the video clips, and notice in some of his other videos he was missing alot of feathers and they were all ruffled, (that is a sign of stress or unhappiness) and also, remember Irene P. did not buy the parrot to be her loving pet, she bought him to conduct experiments because she was a scientist.The facts are... Alex only lived to be 31, he should have lived around 50 in captivity, What we don't know is, how he was being treated and trained without the camera ON!
