Bilbies are one of Australia's most iconic native animals but they're on the verge of extinction due to an abundance of feral cats preying upon them. In a bid to find a solution, University of South Australia PHD Candidate Kyle Brewer developed Population Protecting Implants (PPI) which is a poisonous implant fitted into the bilbies. 30 bilbies at Arid Recovery have had the small rice-sized implant injected under their skin. They are lethal to feral cats but not to bilbies due to a specialised coating, and the marsupials' natural resistance to the toxin. Developer Kyle Brewer explains how he came up with the idea.
