An autonomous machine made in Australia acknowledged as the ‘Felixer’ is proving a critical instrument for ecologists in search of to minimise the menace of feral cats with no endangering native wildlife.
Cats and other released predators like foxes have wreaked havoc with conservation endeavours for many years, so considerably so that most jobs to reintroduce threatened species now only occur on isolated islands where by pests have been wiped out.
Baiting courses have so far proved unsuccessful and often counterproductive as cats want to try to eat prey they’ve attacked on their own, leaving the poisoned baits lying all around for consumption by some other sort of animal.
The Felixer, made by the College of Adelaide’s Dr John Browse, only provides its poison when it detects a cat has approached thanks to the configuration of distinct laser sensors.
“A cat will result in the two center sensors and not result in the leading and bottom sensor,” stated UNSW’s Dr Katherine Moseby, who led a project with Browse where by 20 Felixer gadgets ended up scattered all around a 2600 hectare paddock in South Australia.
“And it also knows the timing of the cat’s stroll so it can detect that a cat is strolling earlier at a standard cat speed.
“So it truly is the sample in which the sensors are broken and the timing of that sample that potential customers the Felixer to ascertain that ‘well, this need to be a cat’, and it fires a gel out via a hole in the side that squirts onto the cat’s flank.”

The Felixer was a hundred percent correct in its identification of cats in the most modern examine.
“All the cats that we ended up conscious of that handed in front of a Felixer through the trial and bought squirted – they all died,” Moseby stated.
That signifies 33 cats, or about two-thirds of the regional feral cat population at the trial internet site eradicated inside six months.
“The kinds that failed to die ended up the kinds that failed to go in front of the Felixer. So if we might remaining the traps there lengthier, we could have possibly eradicated cats from the space.”
The system of supply has an additional failsafe in that the gel depends on cats’ distinctive compulsion to lick their fur thoroughly clean, guaranteeing they ingest the poison and never depart it laying all around.
Moseby additional that realizing other animals won’t be harmed permits the dose of 1080 poison administered by the Felixer to be established to a higher stage to let for a more quickly, more humane loss of life.
The machine could be made use of to ensure rewilding and repopulation courses with threatened species like quolls and bilbies have a possibility on the mainland.
“I’ve been doing reintroductions of threatened species for 20 years and virtually each and every reintroduction try that you do in the wild fails owing to cat or fox predation,” Moseby stated.
“When you see these gorgeous, threatened native species, just time and time yet again remaining ripped aside by cats and foxes, you realise that whilst cats are definitely wonderful animals, they don’t belong in the wild.
“And they are definitely creating enormous impacts to our threatened species.”
