Laboratory cages are much smaller than an animal’s natural home range.

The middle panel shows the ratio of the recommended cage floor area (cm2; Albus, 2012) to the estimated natural home range in hectares (10,000 m2; Nunn and Barton, 2000; Chambers et al., 2000; Bramley, 2014) for eleven species used in research. The left panel shows a juvenile rhesus macaque in a Nepali jungle. The right panel shows a juvenile rhesus macaque in an enriched cage.
