Australia Deploys AI Poison Traps Against Feral Cats
Australia has 2.8 million feral cats. In wet years, that number balloons to 5.6 million. Each one kills approximately 790 native animals per year. Collectively, feral and roaming domestic cats kill 1.7 billion native animals annually. Thirty-four mammal species have gone extinct since European colonization, and cats are the primary driver. Another 120+ species remain threatened.
Australia's response: AI-powered poison traps, night-time cat curfews, 1,600-kilometer predator-proof fences, and a parliamentary report titled "Tackling the Feral Cat Pandemic."
The Felixer Grooming Trap
The Felixer is an autonomous device that uses artificial intelligence to identify cats and foxes by their leg-stride patterns, distinguishing them from native wildlife. When a target animal is identified, it sprays a toxic gel onto the animal's fur. Cats, being compulsive groomers, ingest the toxin within hours. Native animals are unaffected because they do not groom the same way.
The device operates without bait, without human supervision, and without collateral damage. It is currently deployed in predator-free reserves and expanding to broader landscapes.
The Parliamentary Report
Australia's parliamentary inquiry recommended what it called "Project Noah": a massive expansion of predator-free reserves using fenced enclosures and island sanctuaries. The report also recommended night-time curfews for all 3.8 million pet cats, new culling targets for feral populations, and an explicit rejection of Trap-Neuter-Return as ineffective.

Multiple Australian councils have already enacted 24-hour cat containment laws. Wyndham City Council in Victoria expanded its cat curfew from nighttime-only to full 24-hour containment starting January 1, 2026. Merri-bek City Council enacted a 7pm-7am curfew starting July 2026. Fines for straying cats reach $1,600.
The Evidence Is Not Subtle
In January 2025, 25 leading scientists published a rebuttal in BioScience to a paper that tried to claim "little evidence" cats caused Australian extinctions. The rebuttal, led by Professor John Woinarski of Charles Darwin University, showed:
Mammals in cat-free and fox-free havens increased 680% between 2000 and 2017.
Mammals exposed to cats and foxes declined 80% over the same period.

Meanwhile, In America
The United States has an estimated 30-80 million feral cats. There are no federal cat containment laws. Most states have no cat containment laws. TNR is the dominant policy despite the Wildlife Society calling it "controversial and usually ineffective."
Australia is building 1,600-kilometer fences and deploying AI killing machines. America is still arguing about whether feeding feral colonies should be legal.
