An animal breeder breeds animals. This means that they mate animals to produce babies. The breeder then sells these baby animals once they have reached an age where they can survive without the mother. Breeders often work in conjunction with each other to find the perfect mates for each of their animals. Sometimes these animals will only meet during a short mating session. Other times, they may live in the same home.
Animal breeders also care for their animals and the baby animals until it is time to sell them. Breeders also ensure that their animals are purebred, and meet any breed standards or breeding club guidelines. Breeders must sometimes follow strict guidelines in order to reduce the chance for genetic disorders in offspring.
