An animal keeper works at a zoo or other wildlife reserve. As an animal keeper, you ensure that the animals under your supervision receive proper care. Your duties include feeding animals, cleaning and maintaining cages or exhibits, monitoring the animals for any signs of behavioral or health problems, and working with other keepers to make sure facility operations are running smoothly. Qualifications for the job vary. Some animal keepers can find work with a high school diploma or GED certificate, while others seek post-secondary instruction in natural science courses. Observational and animal-handling skills are crucial, so aspiring animal keepers should gain experience working with animals in any capacity.
