Their sociability and intelligence can make African Grey parrots excellent pets. They have a devoted following among parrot owners. However, the same qualities mean that African Greys require a special commitment by their owners to provide frequent one-on-one interaction and supervised time out of their cage. They must be kept entertained and busy with people and toys or they may become stressed and develop self-destructive behavior. African Greys require large cages, a varied diet that includes fresh foods, and plenty of safe and destructible toys. If not provided with these items, African Greys quickly develop unpleasant behaviours and may eventually develop health problems (such as feather-plucking) that are difficult to remedy.
Even the healthiest, happiest pet African Grey will generate a fair amount of mess and noise. Like most parrots, they are non-domesticated, and even a well-socialized, hand-raised, aviary-bred bird is only one or two generations removed from its wild predecessor. Despite this, there is a long recorded history of African Greys being kept by the ancient Greeks, wealthy Roman families, King Henry VIII, Portuguese sailors, and others.
