In the early 2000s, feral cats were a huge problem on Fishers Island, with numbers estimated to be in the hundreds. Contributing to the problem were residents and visitors who allowed their un-neutered cats to roam and breed, or left them behind when departing the Island.
Feral cats can destroy songbird populations, plus there were rumors of Island feral cat attacks on pet cats and dogs, and aggressive behavior toward children.
Responding to the problem, the Fishers Island Conservancy developed a humane response by instituting a volunteer-managed program of trap, neuter and release on the Island’s West End. Additionally, birth control pills were available to caretakers of the three main colonies of cats.
Feral cat “hot spots” were said to be the Transfer Station, the “ordinance” building near Silver Eel Pond, North Hill around to Walsh Park, near the American Legion, Pickett landfill, west of the first hole of Hay Harbor Club golf course, behind the Z&S Station, and several locations an the East End.
Fishers Island no longer has a feral cat issue. After a few years of successful catch, neuter and release, it is thought that coyotes brought an end to the problem.
