Feral cat populations pose welfare challenges for cats, wildlife, and public health. Trap-Neuter-Return (TNR) is widely advocated but its effectiveness is debated.
Feral cat welfare is inherently compromised. Outdoor feral life involves chronic risk of infectious disease, injury from fighting, starvation during poor hunting conditions, and parasitism. TNR stabilises populations without addressing existing animal suffering. Cats in poorly managed colonies may suffer for years. In areas with threatened wildlife, TNR without any removal of cats from the environment does not adequately protect wildlife welfare. The most welfare-positive approach varies by context - in urban areas with no sensitive wildlife, well-managed TNR colonies may represent the best available option.
