Well, I've seen Pac-Man frogs chocke on other Pac Man frogs in breeding facilities, I've even seen them choke on mice. But they were smaller baby frogs.
I wasn't aware that Gray Tree Frogs could grow so large, at least not so large as to be able to choke down a pinkie. I think perhaps the care sheet should have a warning about pinkies and mammalian fat.
I've kept Green Tree Frogs before, but just recently found a cute little Gray Tree Frog....Is a large female Green Tree Frog capable of eating a pinkie?
The care sheet looks pretty good.
