So I have this cat. She's indoor and yearns to murder small animals however I won't allow it.

Problem I'm having is she gets bored of toys really easily, if i find one she likes it will work for a few weeks then she never wants to touch it again. Like I could put the toy away in a drawer for months and bring it out and still no interest.

I've run out of ideas for things to keep her engaged any ideas to try that work well with cats?
