Barn Yarn Animals are Hand-knit Wool Cat Toys filled with Premium Catnip. These are made of 100% wool and are made in the Northern Highlands of South America by descendants of the Inca Indians. The Incas have handed down the craft of knitting through many generations. Chilly Dog directly employs two families to knit their toys and sweaters and practices within the guidelines of Fair Trade. Assorted animals and colors, no two are the same! The average size is 3.5 inches long.
