REALISTIC MOUSE DESIGN: Our cat hunting toy is just like a real mouse, designed to satisfy your cat's hunting instinct and keep it on its paws. The mouse toy for cats makes realistic squeaks when touched. (Size: 7.7x4.7x4 inches, suitable for all breeds of kittens) Mental and Physical Stimulation: All of our cats need mental stimulation from play so they don't get bored. For indoor kittens who like to catch real mice, cat and mouse toys are very popular. They'll feel like they've caught a real mouse and can proudly walk around with the mouse in their mouth, or toss a cat fur toy into the air. EASY TO USE: Remove the plastic cord of the cat toy mouse sound to activate the lively cat toy, and throw the motion-activated pet cat toy on the ground before the mouse makes realistic sounds. Tip: If your cat doesn't notice at first, help tap the mouse to make the noise! Safe and Soft Material: Squeaky cat toys are made of eco-friendly flannelette and electronic components, high quality. Cat toys are also a great choice for cat birthday toys! The battery is not replaceable, in order to prevent cats from eating electronic components by mistake, the battery is not replaceable and the toy can make about 8000 sounds since it is turned on. In order to ensure power storage, the toy has a disposable insulating sheet. Please do not pinch the toy hard before removing the insulating sheet to avoid the separation of the battery and cause no sound.
