This smart rolling ball is perfect for dogs and cats to play with indoors. With a simple button press, it moves randomly and lights up with colorful LED effects to grab your pet's attention. If your pet stops playing, it automatically goes into sleep mode after 5 minutes to save battery. The ball has a unique 53mm diameter, designed to fit all dog breeds' mouths comfortably. Made from durable, bite-resistant TPE soft rubber, it’s tough yet safe and easy to clean—just twist it open to wash the outer shell. It comes with a 300mAh battery, charged via a Type-C port, offering 1 hour of playtime on a single charge. You can choose between two colors, orange and blue, to suit your pet's preference.
