Great toy, and we worked out how to fix it if it starts to spin
Our cats love this toy, but we've had the same problem as some other reviewers, when the butterfly starts to spin around really fast, and doesn't flutter any more. My husband is an engineer and worked out how to fix it. Here's what to do: 1. Ensure the wire is a loose fit in the white plastic button it's attached to, ie the wire should move freely within the button, before you attach the button to the base. 2. Bend the wire in different places, esp. at the butterfly end, until it flutters.
