Kittens grow through play and companionship. From the moment they open their eyes, they learn everything, how to chase, communicate, and control their bites, by interacting with their siblings. When a kitten is raised with a playmate, it learns boundaries, gains confidence, and feels secure. That’s why many shelters and animal behaviorists recommend adopting kittens in pairs, especially when they’re under four months old. Having a friend helps them release energy, stay stimulated, and avoid loneliness or boredom, which can lead to scratching, crying, or destructive behavior. As the understanding of animal emotions has evolved, the idea of adopting two kittens together has become more popular. People recognize that cats, while independent as adults, are deeply social in their early months. Two kittens often grow into calmer, happier cats that adjust more easily to their environment. They play together when humans are away, comfort each other during changes, and even help with training, as one kitten often encourages the other to eat or explore. Still, this isn’t a one-size-fits-all rule.
