Many people like to use lose bedding like aspen, Carefresh, and paper pellets. I used to use these and I liked them, but my Pigs always threw their bedding out of their cage! So now I use fleece bedding. Yes, fleece, just like you would buy in a craft store. I buy mine at Wal-Mart, they have a lot of interesting patterns. It's easy to use fleece in a C&C cage. Here's how to use the fleece bedding:
1st: Place down some absorbent towels or bath mats. (I bought bath mats at Wal-Mart for just $5 each)
2nd: Place the fleece over the towels and leave some remaining fleece hanging off the side of the cage.
3rd: Use kitchen clips to secure the fleece.
This is an example of one of my cages with fleece as bedding^ Fleece is easy to clean and attractive too!
