I had this thought that If he was eating 5-7 every other night that If i gave him one big one it would satisfy his hunger quicker and I wouldnt have to chase these little teeny weeny crickets around my kritter keeper lol!
That is not the way to think. Feeding food items that are to large can be dangerous. Adult crickets heads are armored and cannot be digested. They can cause an impaction if the frog is not large enough to accept them.
