Watched a White's gulp down a live pinkie the other day, fed by a knowledgeable amphib keeper. The frog had been in a tank with two larger males and was not getting it's share of food and was very skinny. He will treat this frog for parasites and probably continue to feed a pinkie occasionally but the daily diet is large crickets. I have a very hard time feeding live mice but will do it if necessary. Only one of my redfoot torts will eat a pinkie. I have no plans on feeding pinkies to frogs (yet).
