So I know this is kind of an odd question. I recently got myself a blue tongue skink and in his enclosure I put as decoration an old sheep bone I found many years ago on a field and kept in my curiosity collection. Yesterday I observe him actually trying to chew on the bone like a dog. Is this maybe because in the wild they’re scavengers and he hoped there’s still a bit of flesh on it? Or was he maybe smart enough to recognize it as a calcium source? I took the bone out for now since I’m worried this might be bad for his teeth.
