What can I do to help my guinea pig regain her sight or live with blindness?

Things are different for your guinea pig now and you MUST treat her differently.She has to come into the house in a cage that will be easy for her to learn where every thing is and is self contained. It is just to big outside and she will be getting lost and not make it to her food and water.Her days of living outside are no more unless you want her to die. Please get her a cage she can quickly learn where every thing is and love her a lot so she does not feel lost in the change. If you give her plenty of loves she should do well.
