However, it's important to remember that kittens raised indoors may never develop strong hunting instincts. This is because they haven't had the opportunity to learn from their mother or siblings. Even if they do develop these instincts, it's crucial to supervise them around small animals and to provide them with safe and appropriate outlets for their hunting urges, like toys.
