When it comes to bedding, there are all sorts of products to choose from. Some guinea pig owners use towels or paper, but pine shavings and pellets are also among the most commonly used types of bedding. Others have been known to get pretty creative, lining the entire cage bottom with fleece or towels.
The bottom line is that you have to find what works best in terms of cost and comfort for your pet. Whatever you do, remember that keeping it clean is vital to your guinea pig’s health.
