The cat springs have saved both me and my kitten's lives I think :D I can get her going with that and she'll enjoy herself for ages.

ope I'm sorry! I'll edit the post to include that - here they are for good measure: https://www.amazon.com/dp/B000CMKHDG?ref=nb_sb_ss_w_as-reorder-t1_k0_1_11&=&crid=MMWWY853WIXW&=&sprefix=spring+toys
These are the exact ones we buy. But tons of dupes on Amazon!
Disposable straws were always my kitty's favorite - very cheap and if she tears them up you can just throw another one at her.
You could also give these toys a shot - they fling themselves around when played with so I've seen kittens go insane for them
Whoops it looks like I messed up the link for the spring toys. These are what she loves: https://www.amazon.com/dp/B000CMKHDG?ref=nb_sb_ss_w_as-reorder-t1_k0_1_11&=&crid=MMWWY853WIXW&=&sprefix=spring+toys
