  abstract = {{I}ntroduced predators on islands are responsible for numerous native species extirpations and extinctions. {P}redation by cats is particularly detrimental to seabirds and cat control or eradication is generally the best option to reduce their negative impacts on native fauna. {H}owever, potential cascading effects, such as mesopredator release effect, need to be monitored after cat removal. {I}n {P}ort-{C}ros {I}sland, a cat control campaign was undertaken to eliminate the strong and recurrent threat from feral cat predation to the small yelkouan shearwater {P}uffinus yelkouan population, without harming a neutered domestic cat population. {T}o evaluate the conservation value of this campaign for an island endemic and endangered species, the diet and impact of the remaining domestic cats were studied through scat analysis and trap success. {M}oreover, to evaluate the recovery of the seabird population and detect any potential mesopredator release effect, shearwater and rat populations were monitored before, alongside and after the cat control. {O}nly live traps were used, and most cats were trapped in the first year of cat eradication. {T}he last incidence of cat predation on the yelkouan shearwater occurred the following year. {T}he recovery of the shearwater population, occurring the first year of cat control, was mainly attributable to the settlement of new breeders in the colony. {R}at population dynamics fluctuated widely but, even though the interactions between rats and shearwaters at breeding cavities increased, no evidence of rat predation on shearwaters was recorded. {T}hus, cat control on {P}ort-{C}ros {I}sland was a success for native species conservation, proving that such management strategy can induce an increase in the population of the endemic species, here the yelkouan shearwater, without any evidence of a mesopredator release effect.},
