Using the Catit PIXI Treat Dispenser is easy. First, open the inner treat compartment and fill it with your cat's favorite treats or dry food up to 9mm in diameter. Then, place the toy in an open area where your cat likes to play. As your cat bats at the toy, it will wobble and randomly drop treats. You can adjust the slider to make it easier or more challenging for your cat. When it comes to maintenance, simply wipe the toy with a damp cloth every now and then to keep it clean. Be sure to use only treats or dry food that fit the size requirement to avoid jamming the dispenser. And always keep an eye on your cat while they're playing with the toy to ensure their safety.
