The main reason cat runs are designed is to provide a safe
, trouble-free environment for your cat. Rather than worrying about them being run over by a car, or wandering off never to be seen again, you can place them in a place where they can stretch their legs and be happy. A run also protects your cat from predators if you've had their claws removed -- there aren't many animals that would tangle with a clawed cat, but cats are defenseless without them.
