Hello, I have 2 male and 1 female white's treefrogs. The female is such a little piggy she tries to eat anything moving near hear.When she see s me coming she always gets ready to jump at me. Last night she accidently got a little river rock in her mouth and every time I took it out she tried to eat it again. I will try to take those out for next time but what if she has already swallowed 1? Would she throw it up? or be smart enough to spit it out before she swallows it?
