To use the KONG Cat Interactive Rainbow Scrunchie, simply toss it for your cat to chase, or wave it around to get their attention. You can also hide it and let them use their hunting skills to find it. Make sure to keep an eye on your cat during play to avoid any choking hazards. If the toy gets dirty, you can gently hand - wash it with mild soap and water. Then, let it dry completely before giving it back to your cat. Store the scrunchie in a cool, dry place when not in use to keep the catnip's aroma fresh.
