To use this KONG Refillable Critter - Style Catnip Toy, simply take it out of the package and let your cat explore it. If the catnip's smell fades over time, open the re - sealable pouch and add the KONG Premium North American Catnip from the included tube. When your cat is playing, make sure there's enough space for it to pounce and bat the toy safely. Keep an eye on your cat to ensure it doesn't accidentally swallow any small parts. To maintain the toy, you can gently wipe it with a damp cloth every now and then. Store the toy in a dry place when not in use to keep it in good condition.
