Some farm animals such as pigs are more intelligent and sensitive than 3 year olds. Professor Stanley Curtis of Penn States University found that pigs play and excel at joystick-controlled video games. He observed that they are capable of abstract representation and are able to hold an icon in the mind and remember it at a later date. It is also shown that chickens and other animals can mimic what they see on television and learn to distinguish between different shapes. Dogs and cats are unable to do this. Pigs are so intelligent that once a pig saved a boy from drowning. So pigs are able to do just as much or even more then your companion dog or cat.
