Birds with absolutely 0 doubt. Cats used to be my favorite animal, and I never saw how anybody thought dogs were the best animal. I have a pet bird, it is a cockatoo, and yes, a type of parrot. He is extremely intelligent. Says only a few words, my name, hello, good-bye, goodnight, the basics, and is extremely awesome. Just about anybody can come up and pet him; he's so used to people after only a few months. Like I said, he's absolutely awesome. He's rather young yet, only 13 or so years old, so he can get rowdy, likes to chew on things, etc., but he's still the best animal EVER.
