Hmmm, I have always brought those exact same kind of pinecone chews, same brand and all for Alfie. I currently have one in the cage now, he loves to chew on them and toss them on the ground, I have never had problems with these pinecone chews. Archie seems to like the pinecone chew too, I have seen him chewing at it. I will have a look at the link, I just dont get how they are dangerous. By the way sorry if I am a few months late.
