The Rainbow toy is constructed from durable cotton twill fabric dyed in bright rainbow colors and hand sewn in the USA. Each piece is individually stuffed with 100 percent organically grown catnip, with no fillers or plastic parts inside. The cotton twill exterior is built to hold up to biting, batting, and bunny kicking during active play. Colors used on the fabric are non-toxic, and the toy contains no zippers or hard components that could pose a hazard. It arrives ready to use with no assembly required. The toy is intended for solo or supervised play and is not designed to be refilled once the catnip inside loses potency.
