60 PCS 12 Colors Cat Spring Toys, Cat Spiral Springs for Indoor Cats, Kittens Toys Plastic Coil for Swatting, Biting, Hunting

You'll never find a higher hit rate than with these stupid little spirals. Not every cat likes them but a LOT of cats go crazy for them, and if your cat likes balls I'm guessing she'll go for them Also check out tension rod cat shelves perhaps! Low commitment if she doesn't take to them, but they go way higher and create more vertical space than most cat trees
