Feral cats are a huge threat to our native wildlife and agriculture but are notoriously hard to control via shooting, trapping and baiting. We aim to test whether the Felixer, a new robotic grooming trap for feral cats, is safe for native cat-like animals such as the vulnerable spotted-tailed quoll. If it can avoid impacts on these native carnivores, this device could be a vital weapon in the fight against feral cats.
