Things got a little confused during feeding time tonight. Fatty, adult female gray treefrog, had nabbed a cricket from behind and was working on swallowing it. It was still alive and maybe 1/2 of the way hanging out of her mouth when Waldo, adult male gray treefrog who is a little bit (but not much) smaller than Fatty, decided this struggling cricket would be a good prey item. I mean it was upside down and rather helpless looking so I don't blame him.
At the moment he struck, Fatty decided to help the cricket down her gullet with her hand. Waldo, whose aim is normally impeccable, ended up with a mouthful of hand, and had Fattys hand in his mouth nearly up to the wrist. At this point I was somewhat concerned and opened the cage and put two fingers on Waldos shoulders and gently pulled him back. Happily he released her hand and everyone seems ok.
So... does this sort of thing happen often and would it likely have sorted itself out if I hadn't intervened? It looked like an honest mistake by Waldo, but I'm not sure he would have stopped trying to swallow on his own, and this seems like it might have been bad for Fattys hand/arm (he surely couldn't get much more in). I know multitudes of people feed groups of frogs together everyday, so many body parts must end up in mouths they don't belong. I've just never seen it happen, so give me some reassurance!
