The Purro Churro are hand crafted from assorted coloful nylon-cotton blended fabric filled with synthetic fill and bells to make a rattle sound to entice play. They are textured and infused with catnip oil derived from naturally grown Pacific Northwest catnip. Measuring 18 to 18.5 inches in length and 3 to 3.25 inches in diameter, they make a great "kicker".
