How often should a mouse cage be cleaned? - briefly

Perform a full cage cleaning—including bedding replacement and surface disinfection—at least once every seven days, and remove soiled material and uneaten food daily. Supplement with a complete bedding change and thorough sanitization every two weeks to maintain health.

How often should a mouse cage be cleaned? - in detail

A mouse cage requires routine maintenance to prevent disease, control odors, and ensure animal welfare. The cleaning interval depends on several variables, including animal density, bedding material, diet, and health status.

Daily tasks focus on spot cleaning. Remove soiled bedding, droppings, and food remnants from the floor and corners. Replace only the affected areas with fresh substrate. This prevents the buildup of ammonia and reduces the risk of respiratory problems.

Full cage cleaning should occur at least once every seven days for a standard laboratory or pet setup. The procedure includes:

  • Transfer mice to a temporary, sanitized holding container.
  • Discard all bedding and accessories.
  • Wash the cage with warm water and a mild detergent.
  • Rinse thoroughly to eliminate residue.
  • Apply an approved disinfectant, following the manufacturer’s contact time.
  • Rinse again and allow the cage to dry completely.
  • Re‑add fresh bedding, enrichment items, and food.

A deeper sanitation cycle, involving thorough disinfection of all components and replacement of water bottles, can be scheduled every four weeks. This cycle is especially important when:

  • The colony size exceeds five animals per cage.
  • High‑fat or wet diets generate excess moisture.
  • Signs of increased ammonia levels appear, such as strong odor or coughing in mice.
  • Any animal exhibits illness, prompting immediate deep cleaning to limit pathogen spread.

Monitoring indicators helps adjust the schedule. Elevated ammonia concentrations (above 25 ppm), visible clumping of bedding, or persistent foul smell signal the need for more frequent cleaning. Conversely, low animal density and the use of absorbent, low‑dust bedding may allow extension of the weekly interval without compromising health.

In summary, maintain a daily spot‑clean routine, conduct a complete cage wash every seven days, and perform a comprehensive disinfection monthly. Adjust frequencies based on colony size, bedding type, and observed hygiene markers to sustain a clean environment for the mice. « Regular maintenance prevents disease ».
