Wood Shavings (pine, cedar, and aspen) are absorbent and have good odor control.[2] Different textures such as fine cut, soft shreds, or thick cut are used for different animals. Wood shavings can be dusty and contain aromatic oils that can cause respiratory, gastrointestinal, urinary tract, or skin disorders and other health problems in some animals.[2] Aspen and kiln-dried wood shavings tend to be less dusty, plus the oils are removed.
