Zookeepers and many animal caretakers may work outdoors in all kinds of weather. In 1998, there were about 181,000 animal caretakers and veterinary assistants, very few of whom were zookeepers. Most animal caretakers worked in animal hospitals, clinics, laboratories, and kennels. Others worked in animal shelters, stables, pet stores, and local, State, and Federal governments. Zookeepers work in zoos.
Many caretakers work for themselves but a lot more work for a salary and many work only part time.
Most people learn how to take care of animals on the job. Some animal caretakers can take a home-study course. Employers like workers who have had some training with animals before they give them a job. Keepers in large zoos usually must have a college degree in biology, animal science, or a similar subject. They also should have worked with animals before.
