Which material is used for disposable rodent cages for single use?

• A. Polycarbonate
• B. PET
• C. Polystyrene
• D. Suspended cage systems

Answer: (B)

For single-use, disposable rodent cages, the material choice is driven by cost, ease of manufacturing, and the ability to dispose after one use to prevent cross-contamination. PET, or polyethylene terephthalate, fits well here because it can be produced cheaply in large volumes, molded into clear, rigid cages, and supplied as pre-sterilized units. This setup minimizes cleaning and sterilization requirements and reduces cross-contamination risk between studies. Polycarbonate is known for durability and repeated autoclaving, which makes it a better fit for reusable cages. Polystyrene is sometimes used for disposables but can be less durable for handling. Suspended cage systems describe a cage design rather than a material, so they’re not the material being selected.
