This is Estella, a guinea pig that lives at the Harvest Home Animal Sanctuary in French Camp, California. She's lived there since she and her mate Pip were found abandoned by the side of a road.
Estella can't move the back end of her body. So after a successful fundraiser for the project, the staff built a custom wheelchair that permits her to walk around. You can see more photos of her and Pip at the Huffington Post.
