Yoshi my @ 1 y/o veiled has decided to try cannibalism. After downing about 10 small crickets, I noticed him shoot at his own tail. I thought a cricket had gotten on it but he did it again. This time he dragged his tail back to his mouth and started munching on his shedding skin. Is this normal or is it time for a therapist? He does seems to have issues [running away, overeating].
