Found this in Tribble's cage, she's a 3 year old female. I've researched and it looks like a copulatory plug, but she's never been near another chinchilla, let alone a male. Pictured next to a box of matches for size comparison. It's the consistency of dried elmer's glue. (Though I know it's not glue now.) She had one the year before and I had assumed it was somehow a chunk of non-toxic elmer's glue. (Though there is no way for there to have a chunk of glue this large in her cage!)
What exactly is this thing?
