Abstract
Abstract Although the domestic cat Felis catus is implicated in multiple faunal extinctions and threatens many extant species, there is widespread, well‐funded advocacy for desexing unowned cats near human habitation and returning them to site to be fed by volunteers, arguing that this prevents euthanasia, is unlikely to be hazardous to wildlife or a public health risk, and controls non‐native rodents. To the contrary, we present unequivocal evidence that this approach harms cat welfare, does threaten wildlife and public health, and exacerbates rather than controls rodent problems. We argue instead that unowned cats near human habitation can be controlled effectively by intensive adoption and responsible euthanasia when necessary, supported by licensing and containment of adopted/owned cats.
