i did the same thing and now all mine will eat is sented rodents. i had frogs on hand for feeding my SIBs so i offered one and the same thing happened. with in seconds the frog was gone. i have a couple of frogs in a little cup in the freezer with water in them and i just thaw it all together.

i wouldn't worry about it too much. just grab another frog and throw it in the freezer and put some water with it after its dead and thaw everything together and it will eat with no problems!
