Enrichment & Natural Behavior

For this group, useful enrichment includes: deep digging boxes with changing tunnel routes, scatter grain or greens through substrate, provide safe roots, branches or chew blocks, low lookout mounds, seasonally change forage type rather than only changing toys.

Merck notes that food can be an enrichment activity when it remains part of a balanced nutrition plan. That means enrichment should use measured portions of normal food—not a stream of extra calories.

• Make the animal use its body correctly: Prioritize floor area, dig depth and escape-proof edges over climbing height. Provide deep substrate, tunnels or buried boxes, at least two retreat options and low lookout structures. Reinforce corners and floor seams because persistent digging tests every weakness.
• Change routes, not safety. Move a branch, tunnel or forage location while preserving secure shelter and predictable escape paths.
• Reward full-body movement. Place resources so the animal climbs, glides, digs, walks or stretches rather than only reaching through bars.
• Protect joints and feet. Variety should not require repeated hard landings or prolonged standing on wire.

• low lookout mounds
• seasonally change forage type rather than only changing toys
• Use the regular ration. Hide or scatter part of the food that would have been fed anyway.
• Keep difficulty adjustable. The animal should work, but not become unable to obtain enough food.
• Check what was destroyed. Any toy or feeder that splinters, frays or creates a swallowing hazard should be removed.

• Frantic repetition: constant escape attempts or stereotypic pacing can mean the environment is still inadequate.
• Resource guarding: enrichment that causes one animal to block another from food or shelter should be duplicated or removed.
• Weight gain: “enrichment treats” count as food and can quietly become a major calorie source.
• Injury or fear: remove anything that repeatedly causes falls, snagging, panic or hiding for long periods.
• No use at all: make the task more biologically relevant before assuming the animal “doesn’t like enrichment.”
