KI Feral Cat Eradication Program
On this page:
The aim of the Kangaroo Island Feral Cat Eradication Program is to eradicate feral cats from Kangaroo Island. The Kangaroo Island Landscape Board (the Board) is committed to removing feral cats from the whole of Kangaroo Island, starting with the 38,000 ha Dudley Peninsula on the eastern end of the island. Since the 2019-2020 bushfires, the Board has also been controlling feral cats in, and adjacent to, the fire scar on western Kangaroo Island, to reduce the predation of feral cats on recovering native animals.

Why eradicate feral cats?
Feral cat predation is a major threat to the Island's valuable and endemic native animals, many of which are threatened on mainland Australia, including the:
- Kangaroo Island dunnartSminthopsis griseoventer aitkeni also known as Sminthopsis fuliginosis aitkeni (Endangered)
- Kangaroo Island echidna Tachyglossus aculeatus multiaculeatus (Endangered)
- Southern brown bandicoot Isoodon obesuelus (Endangered)
- Hooded plover (eastern) Thinornis rubricollis rubricollis (Vulnerable)
Feral cats also spread livestock diseases (Sarcocystis and Toxoplasmosis) that have a huge impact on primary production and profitability, causing substantial economic cost to the Kangaroo Island sheep industry.
For more information click here to watch a video which explains the detrimental impact feral cats are having on Kangaroo Island’s wildlife and primary industries.

What makes this so exciting?
Should the eradication program succeed, Kangaroo Island will become the largest inhabited island to be free of feral cats — generating enormous benefits to the island's ecosystems and economy.
Eradicating feral cats from Kangaroo Island is a unique opportunity for Australia given its:
- border security (being an island)
- community support for both domestic cat management and feral cat eradication
- long history of feral cat management and research on the island to inform control techniques
- absence of foxes, wild dogs and rabbits from the island
- experience successfully eradicating feral goats and feral deer from the island
- supportive local government on domestic cat management.
Kangaroo Island joins Bruny Island, French Island, Christmas Island and Dirk Hartog Island on the Australian Government's list of five priority islands (announced June 2016) aiming to become feral cat free.
How are we eradicating feral cats?
In May 2020 the eradication of feral cats across the Dudley Peninsula began, starting from the very eastern end (at Cape Willoughby).
As the team progresses westward, permission is sought from landholders to access their land to control cats using a variety of techniques. A permission form outlines the methods we hope to use and the advantages of each. If you are on the Dudley Peninsula and would like to have a look at the control options we hope to use, or fill in the form in advance of us arriving near you, please let us know.
Control work is progressing across the Dudley Peninsula using a variety of techniques. Remote cameras are used throughout the Peninsula to detect feral cats and threatened species to direct control efforts. For more information please see the Dudley Peninsula Feral Cat Eradication Operations Plan: Summary 2021-2025.
As the eradication progresses we are gaining a much better understanding of which control techniques work best in which habitats (woodland, farmland, coastal etc.) and the effort required to remove feral cats from these areas.
We provide regular updates of our progress through:
- our Facebook page Feral Free Kangaroo Island which you can access here
- our feral cat newsletter Nine Lives which you can subscribe to here
- updates to participating landholders.
It is very important for us to know if feral cats are still present behind (to the east of) where we are working, so please check regularly and let us know asap via email (firstname.lastname@example.org) or by using the FeralCatScan app as quickly as possible after sighting (see section below).

Have you seen a feral cat recently?
Please let us know if you see a feral cat on the Dudley Peninsula. Please provide as much detail as you can about what you saw, when and where (as precisely as possible). This information will help us identify hot-spots for feral cats and solutions to the feral cat problem. You can send the information to us two ways either:
1. An app called the ‘Feral Cat Scan’ which has been created to help our community record sightings of feral cats anywhere on Kangaroo Island. You can record sightings, impacts (such as predation on native animals) or control activities in the Feral Cat Scan app. Please register your details and login to record feral cat activity in your local area. Please visit the website or download the FeralCatScan app.
2. Or by emailing us at email@example.com.
If you would like to learn more about trapping feral cats in your area, please download the feral cat trapping on KI brochure or watch this video with a step by step guide for trapping feral cats on Kangaroo Island.

Feral cat proof fence to assist eradication
After more than five years in the making, a feral cat proof fence has been built to separate the 38,000 ha Dudley Peninsula from the rest of Kangaroo Island. This 3 km long fence prevents feral cats from the western side of Kangaroo Island crossing into the Dudley Peninsula, where the active feral cat eradication program is occurring. It also provides a ‘hard edge’ for the feral cat eradication team to work towards as they systematically eradicate feral cats from the 384 km2 Dudley Peninsula.
This fence spans the narrow isthmus (a narrow strip of land connecting two larger land areas) of the island. It has two gaps for road egress. Sophisticated surveillance cameras are being developed with artificial intelligence, to detect feral cats in real time and send alerts to the eradication team when they approach the fence.

As part of monitoring of native species across the Dudley Peninsula, the eradication team have been searching for southern brown bandicoots in places where they have been previously detected, as well as in new spots that have suitable bandicoot habitat. Although most previous locations do not appear to have bandicoots present, these marsupials have been detected in woodland on the southern Dudley Peninsula. If you have recently seen a bandicoot on the Dudley Peninsula, please email the location, number and any other details to firstname.lastname@example.org

Please email email@example.com to advise you have made an EFT.
2. Sponsor a remote 4G connected camera
Sponsoring a remote 4G camera will give you individualised live access to images of Kangaroo Island wildlife and feral cat detections. As the area cleared of feral cats expands across the Dudley Peninsula, the monitoring effort must also increasing dramatically. To remove this labour intensive but necessary part of the work, the team is now using 4G-connected, solar powered cameras coupled with a state-of-the-art artificial intelligence system, which sends real-time alerts whenever a feral cat walks in front of a camera. The team have estimated that just 25 of these cameras saves 40 days of staff time annually!
For a once-off sponsorship donation, you can help in the fight to remove feral cats from Kangaroo Island by adding a 4G camera to the array required as the feral cat-free area expands. As part of your sponsorship, you will also receive unique, real time access to photos of Kangaroo Island wildlife whenever you want!
To be able to monitor all 384 km2 of the Dudley Peninsula effectively, 200 are required. Click here for more information on our partner Nature Foundations donation page.
Thank you for your support!

Responsible (domestic) cat ownership
Did you know that Kangaroo Island has the strictest laws relating to domestic cat ownership in Australia?
Since 2007 the KI Council has implemented strict by-laws governing the ownership of domestic cats. Cats on Kangaroo Island must be:
- contained to your premises (House) unless in a contained run
- restricted to no more than two cats per premises*.
A full version of the by-laws can be downloaded here.
*Registered cat breeders can be given permission from the Council to own more cats. Registration must be made with the Council on an annual basis. Registered catteries are also exempt.
Thank you to our supporters
