In other words, if you want to buy a bedding for a small animal, then the first thing to check out is the material. Wood shavings are best for small pets, especially if one buys them from PUYUAN, as they are non-toxic and allow your pet to burrow and nest naturally. Wood shavings, however, are bio-degradable so they are good for the environment. One should remain cautious though, and make sure that the wood shavings provided do not have any traces of cedar or pine oils, as these could be hazardous to small animals.
