That is VERY good news! Please keep an eye on her, as "not eating" is one of the very worst signs a guinea pig owner can see.
Are you feeding her hay? You will want to get a good brand like Oxbow, or order online from Sweetmeadow Farm or Kleenmama's hayloft. You will probably want to get Timothy hay, unless you are allergic to it, in which case you will want meadow hay or Orchard Grass hay. Guinea pigs need 24/7 access to hay, as it keeps their digestive tracts working properly.
You will also want a good plain pellet food, like Oxbow Essentials.
Also, please read the diet section of this forum, including the Nutrition charts. If you are new to guinea pigs, this will help you figure out a balanced diet (for example, carrots should be a treat, not a regular food).
I've had 2 almost-blind guinea pigs, and they do really well once they figure out where everything is. You can change their cage around for variety, but don't move their food or water bottle, as they need to be sure where these are at all times. You should also talk to them when you go into the room, as they can't see you coming.
If you have other questions, please post. We're a friendly bunch!
