What is the best bedding for mice to ensure their comfort and well-being?

The best bedding for mice to ensure their comfort and well-being is a soft, dust-free material such as aspen shavings, paper-based bedding, or recycled paper bedding. Avoid cedar or pine shavings as they can be harmful to mice. Make sure to provide enough bedding for burrowing and nesting, and clean the bedding regularly to maintain a healthy environment for the mice.
