Cats are semi-solitary and do not naturally form stable social groups. Managing multi-cat households to minimize conflict and stress is essential for the welfare of all resident cats.
Multi-cat households create chronic welfare challenges that are frequently underestimated by owners who value cat companionship but underestimate feline social complexity. Cats that appear to "get along" may be engaging in mutual avoidance — not friendship. Stressed cats develop stress-related illness including FIC (painful bladder inflammation), over-grooming causing bald patches, and appetite suppression. The invisible suffering of a chronically stressed cat in a high-conflict household is a significant welfare concern. Resource provision — multiple feeding stations, elevated resting spots, separate litter areas — reduces competition. Feline pheromone diffusers can moderate social tension. Where genuine incompatibility exists despite management, rehoming one cat may provide better welfare for both individuals than forcing cohabitation.
