Saturday we brought home our little guy Gadget, we are new piggy parents so are unsure if the behaviors we are seeing are normal. We have a set play time every night after dinner and we have noticed during this time some behaviors. He tends to like to nibble on our finger tips, my husbands facial hair, and glasses, he seems to twitch then jump as hes running around his toys, and when he gets startled he runs to me and hides his face against me. He also seems to love my hair ties and trying to get them out of my hair. Are these normal behaviors I'm mainly worried about the twitching but it only seems to happen during play time.
