What is the benefit of using paper-based bedding for cavies?

Using paper-based bedding for cavies is beneficial primarily because it absorbs moisture effectively. This characteristic is crucial in maintaining a clean and dry living environment for the animals. When bedding absorbs moisture, it helps to reduce odors and prevents the buildup of harmful bacteria that can occur in wet conditions. This contributes to the overall health and well-being of the cavies, minimizing the risk of developing respiratory issues or other related health problems.

In comparison, while the other options may have their own merits, they do not directly address the essential aspect of moisture control, which is vital for the comfort and hygiene of cavies. Cost-effectiveness and compostability are important considerations but do not encompass the immediate health benefits provided by moisture absorption. Similarly, being organic may be a plus, but the primary function of bedding in an animal's habitat should always prioritize moisture management.
