Maybe some kind of moisture? I had a sealed bag of grass seed and when I opened it, grass was already growing in the bag. Never seen that before either. Maybe contact them to see if they can explain the why or how?
There's no way moisture could have gotten into the bag. It's always been in a dry place. Unless something happened at the pet shop? I think I will contact them, just to be sure.
