Greater bilbies are critically endangered marsupials whose welfare is protected primarily through predator-free fenced havens that exclude introduced foxes and cats.
Bilbies predated by foxes and cats suffer acute fear and physical trauma before death. Their nocturnal lifestyle and sensitivity means handling for veterinary assessment requires specialist techniques to avoid stress-induced capture myopathy. Within predator-free sanctuaries, bilbies show normal foraging, burrowing and reproductive behaviour that demonstrates welfare recovery from predation pressure. The conservation case and welfare case for predator-free havens are entirely aligned.
