Animals that are held by humans and prevented from escaping are said to be in captivity.[1] The term is usually applied to wild animals that are held in confinment, but may also be used generally to describe the keeping of domesticated animals such as livestock or pets. This may include, for example, animals in farms, private homes, zoos and laboratories. Animal captivity may be categorized according to the particular motives, objectives and conditions of the confinement.
