Why does my snail eat its own shell?
Ingestion of the shell is odd but may signify a lack in calcium thus the snail is satisfing it’s needs by absorbing it’s own reserve. ….. and I always wondered if another reason they do it may be to smooth rough edges on the shell that are irritating them, but that’s just a theory 🙂 Whatever the reason, unless it’s very excessive, they never seem to do much damage.
