I know this may not be the exact right spot for this, but I have a question. My one guinea pig, Jenny (pronounced Ginny), has a bit of an attitude problem. I'm pretty sure she can see fine, and she just attacks her sister when they are out (sometimes in cage but not often) and snuggling with us. I've had to put my hand between them to stop her from biting her sister and got attacked instead. no blood drawn yet, almost. What do I do to help ease her to let her know she doesn't have to attack? Her sister is mellow and gentle and a big sweetheart and Jenny is too, but when she wants to be. HELP PLEASE!
