The physical design of multi-cat households significantly affects whether cats coexist peacefully or in chronic conflict. Understanding spatial principles improves welfare outcomes.
The physical design of multi-cat households is a welfare determinant that owners rarely consider systematically. Most cat households are designed around human needs and aesthetics, with cats expected to adapt to a space that may create constant resource competition and social tension. The welfare science of multi-cat households is clear: adequate resources (one per cat plus one), vertical territory (cat trees, shelves), multiple feeding stations, and visual barriers between key areas reduces conflict and stress. Retrofitting a home with these features is less expensive and more effective than assuming cats will simply sort out their differences. Persistent inter-cat conflict that does not resolve with environmental enrichment may indicate incompatible individual combinations that require permanent separation.
