Observation Site Alpha is the first Community Cat Atlas observatory. Through thousands of photographs and long-term monitoring, the site documents how individual community cats move through and interact with a shared environment in Kingman, Arizona. OSA-C-004 is one of several cats helping reveal the hidden patterns of coexistence that often go unnoticed in everyday life.

For more than twelve years, Community Cat Atlas has documented free-roaming cats in Ensenada, Baja California. From the Mercado Negro fish market to the busy walkways of La Bufadora, community cats remain a visible part of the city's waterfront, markets, and public spaces, offering a unique glimpse into coexistence between cats, people, and the environments they share.
