Does she have a place in the cage that doesn't have the wires exposed? If not, but in a chunk of cardboard or an old towel - the wires are hard on her poor widdle feetsies. We have maize matts we get at Pier One for Miss Hoppy's hutch, even though she's just in there for "bathroom" duty,, and otherwise hopping about the house!

Go to rabbit.org for what hay and other food is okay for her - timothy is good if she's full-grown alfalfa if she's a baby, but otherwise not. Grass hay is also okay.
