Multi-cat households create specific welfare challenges; providing sufficient resources, space, and conflict avoidance opportunities is essential for cat welfare in group settings.
Multi-cat household welfare is frequently compromised by insufficient resources and space to allow cats to avoid unwanted social interaction. Cats that share homes but are not bonded prefer separate access to resources — food stations, water bowls, litter trays, resting spots, and safe entry-exit routes should be distributed throughout the house at multiple levels. Competition for any of these resources creates chronic stress that manifests as urinary disease, over-grooming, hiding, and redirected aggression. Cats that can physically see each other while eating, eliminating, or resting are in stress-provoking forced proximity. Vertical space distributes the usable environment multiplicatively — a household that feels crowded at ground level can feel spacious when full vertical space is accessible.
