If you are able to getting her a kitty friend would be best. Kittens do very well in pairs because they can entertain each other, and taking care of two cats isn't much harder than caring for one.

Try getting her some fun toys to play with, those wands with the feather at the end are great for kittens. THey have so much energy and you need to teach them that your hands aren't toys, so you'll need to redirect her attention.

TurboTracks are also another great toy. I think they run about $10, and they are worth it. Even my two grown kitties still play with it!

Here's a picture of what a turbotrack looks like.
