Which statement correctly describes primary enclosure space for non-human primates?

• A. Space must include swings and perches.
• B. Based on typical weight of species groups 1-6.
• C. No IACUC approval is needed for smaller enclosures.
• D. There is a fixed space independent of weight.

Answer: (B)

Primary enclosure space for non-human primates is determined by the animal’s body size, using weight-based categories that reflect typical sizes of the species. Standard housing guidelines specify minimum floor space based on these weight groups (often labeled 1 through 6), so the space scales with the animal’s size and allows normal movement, turning, and resting. This approach contrasts with a fixed, weight-independent size and with enrichment requirements that are not the primary driver of the space metric. While enrichment like swings and perches can enhance welfare, they are not what sets the minimum enclosure size. Also, housing changes always require IACUC review and approval, so the idea that no approval is needed for smaller enclosures isn’t correct.
