New Zealand's Predator Free 2050 programme targets feral cats alongside rats and stoats, raising welfare considerations for large-scale feral cat management.
Feral cats caught in leg-hold traps experience acute stress and potential injury. Kill traps cause rapid death when properly set. Poison bait (1080) causes internal seizure and death over 30-90 minutes. The welfare of feral cats in management operations is weighed against the welfare of millions of native birds, lizards and invertebrates killed annually. Island eradications have enabled dramatic recoveries of seabird and lizard populations, with net positive welfare outcomes for biodiversity.
