Thank the Lord.
One of my adult frogs swallowed a marble. After two days of frantic worrying on my part because of her size and the size and weight of the marble, she threw it up. I was terrified I was going to lose her. Now I'm going to take out all of the gravel and go to a bare bottom. And then go by the "if it's small enough to swallow and not food, then it doesn't go in" rule. Which I just made up, sorta.
Other than that, nothing.
