When she hears the chain dangling she immediately looks at me and then down at the ground to catch her immortal red bug!
Haha, my cat Coda does this as well.
The "fishing pole" type toys seem like they're pretty universally a hit. If she liked the peacock feather, she'll probably like the fishing pole type toys, too. They come in all sorts of varieties, but the basic design is just a stick with a string attached to the end of it. Some of them have bells or feathers or what have you to make them more fun an eye-catching for both human and feline.
One thing both my cats LOVE (even Cal, who is older and mostly not too interested in play time and toys) is tying a string around a catnip-filled toy and dragging it on the ground for them to chase or dangling it in the air to get them to jump and bat at it.
My mom got my kitties some neat catnip toys for Christmas. They open up and close back up with velcro, so you can replace the catnip inside so you can make sure that the catnip toy is always filled with fresh catnip. My cats LOVE them and when I tie a string around it, they go bonkers chasing after it.
I have several different fishing pole toys, and Coda (our younger, very playful cat) seems to enjoy the variety. When she gets bored with one, I'll just switch out for a different one and she goes crazy for it again. I have one with some sort of frills and bells, one with a bunch of feathers, and one with a catnip mouse on a sort of stretchy bungee cord.
I'm actually not even sure what "Da Bird" is, though I've seen a lot of people on here mention it. I'll have to look into it, but Coda very much enjoys her fishing poles and laser pointer, and she and Cal go crazy for the fresh catnip-filled toys on a string.
Coda also likes those little balls with bells in them (she really likes bells), but she usually plays with those on her own. When I try to toss them for her to chase, she just looks at me like she's saying "Do I look[
like a dog??" Lol.
