This mouse-shaped cat toy is sewn from sturdy cotton twill fabric and packed with organically grown catnip rather than synthetic filler. The fabric is tinted using non-bleed, vegetable-based dyes, giving the toy its bright yellow finish. Each mouse is hand-filled to capacity so cats can nose, bite, and bat the toy to release the scent inside. It is sized for easy carrying and kicking, appealing to kittens and adult cats alike. The toy and its catnip are produced in the United States. No batteries, assembly, or extra parts are needed before giving it to a cat.
