A "catio" is an outdoor enclosure designed specifically for cats, allowing them to enjoy fresh air and sunshine while staying safe from potential dangers like predators or traffic. These structures can vary in size and design, ranging from small window boxes to large, freestanding spaces. Catios often include features like shelves, ramps, and tunnels to keep cats entertained and active. Many cat owners choose to build or purchase a catio to provide their pets with a stimulating environment. By incorporating elements like plants and toys, a catio can mimic a natural habitat, promoting physical and mental well-being for indoor cats.
