I saw a couple Youtube videos where pacman owners fed their frog a rodent that was MUCH too large, and the rodent fought back, biting the Pacman.
It should be common sense- don't feed your frog a mouse or rat that is twice his size. Can't frogs choke to death on their food?
I think once a frog bites down, it's not easy to let go...
Check out this video of a pacman being fed a mouse- this mouse is WAY to big for a frog that size , isn't it? The owner is lucky if his pacman didn't choke to death
