Evidence-based strategies for managing multi-cat households to minimize stress, conflict, and chronic welfare problems among resident cats.
Multi-cat households represent one of the most common sources of chronic feline welfare problems, often invisible to owners who see their cats as coexisting peacefully. Subtle aggression and resource guarding cause persistent low-grade stress in subordinate cats, manifesting as urinary problems, overgrooming, hiding, and reduced play and exploratory behavior. The welfare solution requires thinking about the household from the perspective of each individual cat: do they have uncontested access to food, water, litter, and resting spots? Can they move through the home without encountering another cat? Appropriate resource distribution, sufficient vertical and horizontal space, and environmental enrichment tailored to each cat can transform a chronically stressful multi-cat environment into one where welfare needs are genuinely met.
