An epidemiologist wanted to investigate the prevalence of a specific respiratory pathogen among rescue cats housed in shelters across a metropolitan county. Previous regional data was outdated. The epidemiologist randomly selected 5 shelters from all 18 registered animal rehoming shelters in the county. Four of the five shelters agreed to participate. The epidemiologist performed diagnostic swabs on all rescue cats currently housed in these four participating shelters.
Identify the population the epidemiologist was interested in studying.
