My pigs haven't started "watching" it yet, but I've had to separate them temporarily because the TV.
Bandit loves benig anywhere there's noise. If she's not in the living room with the TV she'll squeal until we put her back near it. Then she popcorns around.
Miss Diva is the opposite. Even across the room, she's afraid of the TV. She'll send out her alarm call and try to hide, climb out of the cage, and physically shakes; you can tell when you touch her.
So she's in my room, while Bandit is in with the TV.
I don't know how I'm going to get them to live together happily again, but they're okay for now.
