The Felixer grooming trap uses sensors to identify cats and foxes, distinguishing them from other wildlife by their silhouette and gait.
It sprays the animals with a dose of toxic 1080 gel which kills them when they lick it off.
The use of the box-shaped device will be encouraged as part of Western Australia's five-year plan to manage invasive feral cats.
Backed by a $7.6 million state budget investment, the plan includes funding to increase aerial baiting by more than 45 per cent with a focus on conservation reserves including the Stirling Range National Park.
It will also fund research programs and conservation projects, while traditional owners, community groups and rural property owners dealing with feral cats will receive additional grant assistance.
Environment Minister Reece Whitby said feral cats were the most destructive species in Australia, costing the nation $300m per year in damage and mitigation measures.
Dozens of mammal, reptile and bird species in WA are vulnerable to the predators.
"The WA Feral Cat Strategy is the first of its kind in the country," Mr Whitby said on Wednesday.
"Feral cats wreak a devastating toll on native wildlife in Western Australia.
"This strategy represents a major effort to control this pest and gives struggling native species a fighting chance of survival."
Described as expert predators, feral cats were declared a pest in WA in 2019.
They are monitored through aerial tracking, GPS collars and cameras.
"Feral cats don't just live in our national parks, they're on our farms and in deserts, wetlands and woodlands," Mr Whitby said.
"We need to work together, use new technology and think outside the box to outsmart these predators and protect what makes our state so unique."
