What group includes marmosets and tamarins when determining cage size requirements for nonhuman primates?

The group that includes marmosets and tamarins, when establishing cage size requirements for nonhuman primates, is classified as Group 1. This classification is important because the Animal Welfare Act (AWA) sets specific standards based on the species and size of the animals, which directly impacts their care and housing needs.

Marmosets and tamarins, being small primates, have certain space requirements that differ from larger primate species. Group 1 generally includes smaller nonhuman primates, and the regulations provide guidelines to ensure they have adequate space to move, exhibit natural behaviors, and be housed in an environment that promotes their well-being.

Understanding these group classifications allows for better compliance with welfare regulations and helps facilities maintain the required standards for the humane treatment of these animals. Thus, recognizing that marmosets and tamarins fall within Group 1 is crucial for ensuring their appropriate care and housing under the AWA.
