A pet is an animal that is a companion to its owner. Unlike other livestock animals such as cows, sheep, and chickens, which are used for their meat, eggs, milk, wool, or feathers, pets are kept primarily for their companionship. In the past, many children were given dogs as pets in order to learn responsibility and to develop a sense of caring for another living thing. The bond between children and their pets has been celebrated in myth, art, and literature with the likes of Rin Tin Tin and Lassie.
Most pets, particularly mammals such as cats and dogs, are devoted to their owners and provide affection and comfort for them. In return, the human owners provide food, water, and exercise for the animal. Pets can also be a social lubricant for their owners, helping them meet other people on walks or in dog parks. They can also help ease the anxiety of people who have trouble leaving their homes or who are afraid to go out in public by providing comfort and reassurance.
Some people keep animals such as rabbits, rats, guinea pigs, and hamsters as pets in addition to dogs and cats. However, these pets are often bred in massive warehouses and sold to people who do not have the space or expertise to care for them properly. As a result, many of these animals live in conditions that can lead to disease, illness, and premature death.
