Intact carcasses as enrichment for large felids: Effects on on‐ and off‐exhibit behaviors

Abstract

AbstractReducing stereotypic behaviors in captive animals is a goal for zoological institutions worldwide, and environmental enrichment is one tool commonly used to meet that end. Behavioral needs associated with feeding, however, are often neglected in large carnivores. To address these needs, I tested the effects of calf carcasses as enrichment for large felids. Over 14 weeks, I provided nine animals with up to seven intact carcasses. The cats were housed at Toledo Zoo, Potawatomi Zoo, and Binder Park Zoo. Animals were observed off and on exhibit for changes in feeding, natural, stereotypic, active, and inactive behaviors. I compared treatment behaviors with behaviors observed during a baseline period in which the animals were fed traditional processed diets. For these nine cats, carcass provision decreased off‐exhibit stereotypic behaviors but had little impact on on‐exhibit behaviors. Zoo Biol 21:37–47, 2002. © 2002 Wiley‐Liss, Inc.
