Which statement about environmental enrichment is true?

• A. Enrichment aims to promote natural behaviors and welfare
• B. Enrichment is optional and should not be considered in welfare
• C. Enrichment is only for non-mammalian species
• D. Enrichment is prohibited in some cages

Answer: (A)

Environmental enrichment involves providing stimuli and opportunities that allow animals to perform natural behaviors and engage in activities that promote mental and physical well-being. This is the best description because it links enrichment directly to welfare, recognizing that giving animals ways to express instinctive behaviors reduces stress, prevents boredom, and supports health and learning. Enrichment isn’t optional or something added only for fun; it’s a fundamental part of proper care tied to welfare standards. It isn’t limited to non-mammalian species—mammals and other groups also benefit from appropriately designed enrichment. And rather than being prohibited in cages, enrichment features are typically integrated into housing to improve the animals’ quality of life. For example, providing nesting material and hiding places for rodents or foraging devices for birds helps them express normal behaviors and stay mentally engaged.
