The chapter ’Virtual Furever Homes’ shows the background of digital spaces and community building by using examples from cat-related digital spaces. The evolution of participatory culture and the development of technology have influenced the way we form online networks and communicate with each other. The chapter explains the concepts of virtual communities, communities of practice, light communities, and affinity spaces. As digital spaces form around narratives, it uses the shared story of the mediated narrative approach to categorise the types of cat accounts that make up the cat-related digital spaces.
