Many keepers go to college for 2 or 4 years. They often study biology, animal science, or some other science. Keepers also need to understand math so that they can measure food properly. Keepers need good writing and speaking skills, too, so that they can take notes and talk to the public.
Keepers also need experience caring for animals. Before working at a zoo, many keepers work in veterinary offices, in pet stores, or on farms. In those jobs, they clean animal cages and feed, watch, and care for animals.
Experience in a zoo is also good. Many keepers start as zoo volunteers.
