I understand that using softwood shavings (pine not cedar) for rodent bedding can have negative consequences in the form of elevated enzyme levels in the liver and also possible respiratory problems.
However, it is not clear to me that there are, or are not, negative consequences of feeding rodents that have been raised on softwood shavings to my boa constrictors. I have been using kiln dried softwood shavings without visible affects to the rodents.
I typical freeze and thaw as required although sometime I go directly from CO2 euthanasia to feeding (fresh killed).
Can those of you knowledgeable in this area tell me if there would be a possible negative consequence to my snakes if I continue with this practice?
Thanks

Though poplar is a kind of tree as well. We have alot of them up here in Canada. Aspen is a completely different tree than poplar. There is a kind of poplar which, I beleive, is called American Poplar which grows about 5-8 feet a season, perhaps this is the kind you are referring to. It's a 'hardwood' as well. If I am correct, coniferous trees (ie cone bearing, like pine trees) are softwood, deciferous trees are hardwood.
