Cats often like a stroll outside, but that can cause some stress for their owners. To keep his feline friend safe, close to home and happy, one Japanese cat owner built this awesome fenced outdoor catwalk around the walls of his house. The creation makes sure that the cat can get some fresh air, but stay where you could always find it. Gotta admit, in a country with a shortage of space for people and pets alike, this structure is a really great idea! (via laughingsquid, Nekomomo)
