No butts about it. Iʻm hoping that one of the kids actually did his job and threw it away when cleaning Chefʻs enclosure. I asked the teacher to let me know if anyone found it. Itʻs been over two weeks, so Iʻm hoping it passed, and I missed it, and itʻs not stuck somewhere in his G.I. tract. Heʻs eating and farting just fine. And as you can see from the picture - pooping just fine too!
