What should be used to treat a rat cage? - briefly
Use a diluted bleach solution (≈10 % sodium hypochlorite) or an enzymatic cleaner, then rinse the cage thoroughly with water. Follow with regular application of an EPA‑registered rodent cage disinfectant.
What should be used to treat a rat cage? - in detail
Treating a rat cage requires a systematic approach that eliminates pathogens, removes waste, and preserves the integrity of the enclosure.
Begin with a complete removal of bedding, food remnants, and droppings. Dispose of the material in a sealed bag and replace with fresh, absorbent substrate such as aspen shavings or paper-based bedding.
Clean the interior surfaces with hot water (≥ 60 °C) and a mild, non‑ionic detergent. Rinse thoroughly to prevent detergent residue, which can irritate the animals’ respiratory system.
Disinfect the cage after cleaning. Effective agents include:
- Diluted chlorine bleach (5 % sodium hypochlorite) at a concentration of 1 % (one part bleach to nine parts water); contact time of at least 10 minutes.
- Quaternary ammonium compounds labeled for use in rodent facilities; follow manufacturer‑specified dilution and exposure time.
- Hydrogen peroxide (3 %) with a contact period of 5 minutes; suitable for plastic and metal components.
After disinfection, rinse the cage with clean water and allow it to air‑dry completely before reassembly.
Inspect all accessories (water bottles, food dishes, tunnels) for cracks or wear. Replace any damaged items to prevent injury and bacterial colonisation.
Apply a protective coating to metal parts prone to corrosion, such as a thin layer of food‑grade silicone spray. This prolongs the lifespan of the cage and reduces rust formation.
Finally, establish a regular maintenance schedule: daily spot cleaning, weekly full cleaning and disinfection, and monthly inspection of structural components. Consistent implementation of these steps maintains a hygienic environment, supports rodent health, and complies with laboratory animal care standards.
