Cats are a fundamentally solitary species whose social needs in multicat households are frequently mismanaged, causing chronic stress that affects health and quality of life.
Multicat household welfare requires recognizing that bringing multiple cats into a home imposes the burden of tolerating social proximity on animals who did not choose cohabitation. Cats who live together in chronic low-level conflict — manifested as resource competition, subtle intimidation, and spraying — suffer real welfare harm even without obvious fights. The welfare framework for multicat households centers on resource abundance (eliminating competition triggers) and spatial complexity (allowing cats to avoid each other when needed). Owners who interpret cohabiting cats as companionship without assessing behavioral indicators of stress may inadvertently maintain chronic welfare deficits in their animals.
