I know of the teeth chattering to other pigs showing dominance but do they do a very milder version to us mommas? A couple times bevo will start chewing although he's not chewing on anything and its lightly but it reminds me of the chattering. And he has done it while just laying on my chest. He appeared happy. Is this teeth chattering or something ekse? I hope I'm not making him upset. I can't see why I would be.
