My guinea pig has been alone for about a year now (so that's not the problem, and don't worry she still gets to socialize because my friend also has a pig and they get along well) and she's been talking to herself all of a sudden? It doesn't sound like pain, but at the same time it does, or like crying. It's weird. And she's also hunched up in random places of her cage. But she eats, drinks- She acts normal except those two things.
