Arguments for letting cats roam outside include natural behavior expression, physical exercise, and mental stimulation. Outdoor access can contribute to a cat’s overall happiness and well-being by allowing them to explore, hunt, and play. However, arguments against it emphasize increased risks of injury, diseases, predator threats, and accidents. Outdoor cats can also negatively impact wildlife populations, especially birds. Given these considerations, many experts advocate for supervised outdoor activities, such as leash walks or secure cat enclosures, to balance safety with the benefits of outdoor exposure.
