Using these cat toys is easy! Just give the toy to your cat and watch as they bat it around and enjoy the fun sounds. When the batteries run out, simply replace the two 1.5V Alkaline Batteries. It's important to always supervise your pet when they're playing with the toy to ensure their safety. To keep the toy in good condition, keep it clean and away from sharp objects that could damage it. Also, note that the style you get depends on what's in stock, so you might get a different style than you expected, but all of them are great for your cat!
