I read somewhere on the forum that dried pine cones from the woods were ok for squirrels as a toy, and I gave my Reba one, and she absolutely shredded it, but I was just looking around on the site for info about green ones, and I saw that they should only have unopened green or brown cones. Is she in danger because I gave her an older one? Her stomach seemed a little tighter tonight than usual, and she was sleepy earlier than usual. I tend to worry for nothing sometimes, but I don't want to have given her something that will make her sick. Any advice?
