Common Misperceptions About Pine Bedding

"Pine releases toxins”– the naturally occurring aromatic hydrocarbons (also know as “aromatic oils”, or phenols) in pine shavings have not been demonstrated to be detrimental to small animal health. In any event, the heat treating (kiln drying) of the wood fiber which is part of the manufacturing process significantly reduces these hydrocarbons.

“The phenols or aromatic oils in pine cause liver damage” - Changes to liver enzyme levels, usually cited by opponents to pine, are not a sign of damage to the liver. An often cited study, Cunliffe-Beamer – 1981, studied mice injected with barbiturates to measure sleep time. People citing this study rarely mention that liver enzymes can be elevated by common environmental factors such as food, or that these changes can be part of normal bodily functions.

The articles most often cited on why pine is not an acceptable bedding are "The Toxicity Of Pine and Cedar Shavings" (Debbie “The Rat Lady” Ducommun) and “The Problem With Pine – A Discussion of Softwood Beddings” (Elizabeth R. TeSelle of the American Fancy Rat and Mouse Association). Their interest in, and commitment to, small animals is not in question, but they are expressing opinions, not offering independent, peer reviewed information. It is interesting to note that each of the above referenced articles end with an endorsement of a leading paper pulp bedding.
