What is environmental enrichment?
Environmental enrichment involves providing a stimulating environment for laboratory animals to enhance their well-being and health.
How does environmental enrichment affect mice?
It promotes metabolic health, reduces adiposity, and enhances resistance to obesity and cancer.
What materials are used in the enrichment setup?
Materials include wheels, tubes, logs, and various toys to create a stimulating environment.
How often should the environment be cleaned?
The environment should be cleaned regularly, with weekly maintenance and thorough cleaning every three months.
Can multiple mice be housed together in the enriched environment?
Yes, 10 to 20 mice of the same age, gender, and strain can be housed together in the enriched environment.
What are the signs of distress in mice?
Signs include lethargy, lack of appetite, and abnormal behavior. Daily monitoring is essential.
