Managed feral cat colonies present welfare challenges for colony cats — outdoor living with variable food access, disease exposure, and weather creates chronic stressors even in well-managed colonies.
Feral cats in outdoor colonies experience welfare compromises that managed care mitigates but cannot eliminate. Weather exposure, infectious disease from colony contact, injury from territorial fights, and the chronic stress of predator vigilance all impose welfare costs that indoor cats are protected from. Well-run TNR programs with consistent feeding, veterinary care, and monitoring provide the best achievable welfare for cats that cannot be socialized for indoor placement. The ongoing welfare challenge is ensuring colony management quality rather than simply whether management occurs.
