Table 1a. Hypothetical welfare audit scenario.

You are participating in a welfare audit in an institution housing approximately 500 macaques. Individuals are housed indoors in 25 animal rooms which each hold 5 racks; each rack holds 4 cages and each cage houses 1 animal. Animals are either singly housed with access to one cage or are socially housed in pairs or groups with access to multiple adjacent cages (1 per animal) with a single rack; some individuals are participating in active research studies.
