I wasn't sure the silvervine would do anything, but my cat was rolling on it within a minute. The bright LED lights are a fun bonus once she starts kicking it around at night.

The LED lights kick on the second my cat bats at it, and she's been chasing that glow around the living room for twenty minutes straight. The kicker shape is perfect for her to grab and bunny-kick, and the catnip has her fully obsessed.

The silvervine filling got my cat interested way faster than plain catnip toys ever did. Only downside is the plush picks up a lot of fur, but it's holding up well after a couple weeks of daily kicking.
