An inexpensive Plexiglas metabolism cage for the squirrel monkey (Saimiri sciureus)

Area of Science:

• Primate research
• Animal husbandry
• Laboratory animal science

Background:

• Efficient and non-intrusive metabolic monitoring is crucial for primate research.
• Existing metabolism cages may present challenges in sample separation, maintenance, or behavioral impact.

Purpose of the Study:

• To describe a novel, cost-effective metabolism cage specifically designed for squirrel monkeys (Saimiri sciureus).
• To detail the cage's features facilitating efficient sample collection and ease of use.
• To present methods for minimizing sampling error and preliminary study results.

Main Methods:

• Detailed design specifications of the novel metabolism cage.
• Description of standard laboratory procedures for reducing sampling error.
• Presentation of data from a pilot study utilizing the apparatus.

Main Results:

• The described cage is light, sturdy, and inexpensive.
• It allows for efficient separation of urine and feces.
• The design minimizes interference with squirrel monkey behavior and is adaptable for other small primates.

Conclusions:

• The developed metabolism cage offers a practical and economical solution for squirrel monkey research.
• Its design promotes accurate metabolic data collection while respecting animal welfare.
• The cage's adaptability suggests broader utility in small primate studies.
