Ladybugs are wacky and cheerful. A yoyo fits them! Cats are majestic and tend to glare at people at random. Staves aren't the first weapon one would think for a cat superhero.

[No points for guessing that yes, claws are the first weapon to come to mind]

It'd be as if Batman got a hammer as a weapon, it just feels kind of weird to think about it.
