Feral cats are a menace to wildlife but South Australia’s KI has taken a stand in a bold eradication program that is at a critical point
When there are a lot of cats shooting/trapping them is easy. When 1% are left it is harder and if they breed the eradication program is in danger of failing.
Quote:he cat-proof fence drops off a sheer cliff on one side of Kangaroo Island, and disappears into the ocean on the other. The top section is floppy and electrified – a rude shock for wily cats seeking to climb over – and the bottom is burrow-proof.
Gaps left for humans and wildlife funnel any would-be trespassers through a minefield of traps, which are closely monitored.
Kangaroo Island’s 38,000 hectares Dudley Peninsula eradication program, run by the KI Landscape Board (Kilb), has decimated the island’s feral cat population from a high of about 1,600 to approximately 150, although it’s hard to pin down precise numbers.
Cat-detecting dogs, drones, artificial intelligence, and thermal optics all play a role, as does the feline hotline, where residents can report a cat sighting.
Fencing off an area is essential to local feral cat eradication.
