Go Cat makes several attachments for the Da Bird cat toy(and compatible poles). This is the Super Refill.
Made in the USA, the super refill has more twirling action than the original guinea refill and an extra feather to help make the movement more exciting to your cat!
Easy to connect to the existing string on your Da Bird compatible interactive rod/pole/wand.
Each is made with 3 natural (not dyed) guinea feathers and has colored accent feathers to give it that added flash. The accent feathers come in blue, lime, green, red, pink, orange, turquois and purple. One color accent is used per refill.
Colors and feather length vary.
