I am reading conflicting responses online so I thought I would come here to where the pros were! I was just given a big bag of cinnamon sticks from a friend who is moving. She used to grind fresh cinnamon from the sticks when she was baking but I do not have the patience for that!!! They look pretty in a container on my shelf and it seems such a waste to throw them out! I was thinking, my rabbit and my hamster get little twigs and blocks of wood to keep their teeth in check, wouldn't this just be like any other twig? Any thoughts?
