Small mammals including meerkats, otters, red pandas, and fennec foxes are popular zoo exhibits, but their welfare needs are often underestimated due to their small size.
Small mammals are frequently housed in smaller, less costly enclosures than large charismatic species, but their welfare needs are no less complex relative to their natural behaviour. Otters require access to water for swimming and foraging; red pandas need vertical space and suitable temperature ranges; meerkats need social groups of appropriate composition. Failing to meet these needs causes the same stereotypic behaviours and chronic stress seen in large species, but in animals that receive less welfare attention.
