The cat teaser is designed to appeal to a cat's natural instincts to play, pounce, and hunt. 
 
When introducing a  cat toy to your cat, it's important to monitor their behavior and ensure they are not playing too aggressively and potentially harming themselves or others. Additionally, not all cats may be interested in the toy, so it's possible that it may not be effective for all cats.
Overall, the cat toy can provide cats with a fun and stimulating way to play and satisfy their natural instincts. However, as with any cat toy, it's important to choose toys that are safe and appropriate for your cat's size and behavior, and to supervise their play to ensure their safety.
