Is it normal for new piggies to bite? Mine chews on me all the time. And she bites my chihuahua >_> I'm getting a bit stressed out because she was fine and didn't bite hard for the first few days but today she just bit me really hard like 5 times.
She obviously doesn't like being crowded - try and get her used to others by talking to her and have sitting in a cuddlebed or and upturned pigloo where she can feel safe while she's on your lap. An use an oven glove at first while you're shooing her in an out of it in the cage!
An agressive biter like yours feels threatened; so take it very slow and easy with her. Once she is more at home, she will relax and bite a lot less. she might always be a bit of a tweaker, if you're unlucky.
