Da Butterflier Cat Wand Toy by GoCat (makers of the Da bird).

It's Time for the Birds and the Bees and Da Butterflier!

Made in the USA, the Go Cat Butterflier Teaser Wand has a 2 1/2" feather butterfly attached to a wire connected to a 6" glitter wand, totalling 20" in length.
Another fantastic toy to interact with your kitty for play and exercise.

Comes in various colours.

This toy is intended for supervised interactive play only.
For best play action, hide the toy when not in use and bring it out periodically for play sessions, to simulate prey appearing somewhat randomly.
Make the toy move like prey. It should subtly twitch and freeze, as well as make mad dashes across the room. Try to time the toy's movements with your cat's stalking and pouncing to maximize the thrill of the chase and to allow plenty of captures.

TIP - If you attach the short wand that comes with the toy with two strips of selotape to the longer Da bird wand, Da Butterflier will fly in a wider range. ;) To make the butterflyer toy last, allow light captures and try (notice the word try! ha ha) to aviod your cat completly chewing the butterflyer end.
