Using these KONG Artz cat toys is easy. Just give them to your cat, and watch as it starts batting, pouncing, and chasing them. For solo play, you can simply leave the toys around the house where your cat can find them. If you want to play with your cat, hold the toy by the ribbon and move it around to mimic the movement of prey. When it comes to maintenance, it's a good idea to check the toys regularly for any signs of wear and tear. If the toy gets dirty, you can gently hand - wash it with mild soap and water, then let it dry completely. Keep these toys away from other pets that might chew them up. Also, if the catnip loses its potency over time, you can replace it to keep your cat interested.
