I went to Petsmart today to buy a new water bottle, since mine magically leaked an entire bottle of water into Mimi's cage overnight, and I seen a type of chew toy that had a pine cone on it and it said it was safe for chins?? Everything else on there was chin safe, or I would assume. It's being sold at Petsmart so I can't really say much. It had wood and loofahs on it, but a pine cone in the middle. Now correct me if I'm wrong, but I don't think pine cones are chin safe?
