We buy a big bulk bag of pine shavings for our 5 chickens, and we have always bought aspen for our small animals.... but I've heard pine smells and absorbs better than aspen. I have also heard pine can kill hamsters because of upper respitory problems? I've known pine bedding to be used forever for small animals.... but now i'm not sure if this is threatening my pets? Does anyone here use pine bedding for rabbits/hamsters? And do you have any opinions on this topic? I know cedar is deadly and i would never use it, but pine?
