Walking a cat on a leash provides significant benefits, including safety and exercise. It allows cats to explore the outdoors while minimizing risks associated with free roaming, such as cars, predators, and toxins. This controlled exposure to the outside world can enhance a cat's mental stimulation and physical health. Additionally, leash walking serves as a bonding activity between cats and their owners, fostering a deeper connection. It's essential, however, to ensure the cat is comfortable with a harness and leash through patient training for a positive experience.
