In order to prevent physical and psychological deterioration in older animals, it is important to apply the same principles of environmental enrichment and housing as are applied to younger animals. As we have discussed above, the needs of aged individuals can be highly specific and may be markedly different from those of younger animals of the same species. Therefore we have listed some of the key aspects of environmental enrichment and housing that those who are housing older primates should consider in order to preserve the health and well-being of the animals in their care.
