I would get her something like a feather wand, so you can play with her and interact with her. Or a little mouse toy, or busy balls with bells inside. Most cats will appreciate any new toys you give them, even though they may lose interest in a day or two.
No matter what the toy, I think if you actively play with her and the toy and make it interesting, she'll probably gain interest even if temporary. My cat could ignore a toy for a long time, then all of a sudden start playing with it again. The best toy he loved was the natural mouse that had a realistic squeak when you just touched it, but after the dog got hold of it, I found that it had a button battery and read up on their safety. I decided to throw it out.
