Thanx that helps. I really thought she could be lonley. She is really hyper-active sometimes and she goes running like crazy all around the cage. Right now I have corncob bedding, but next time I am going to get pine cuz she cant really dig in corn cob, so maybe that is why she is scratching all in her tubes. I also brought her over to my friends house (her gerbil is my gerbils mother) and we let them play with eachother and my gerbil didnt seem to be that happy to be with her mom LOL her mom also attacked her when we put them in her cage! So we decided never to put them together again.
