A recent research project has uncovered a novel method of using sound as a harmless deterrent to keep cats away from nesting native birds. Senior scientist at the Bioeconomy Science Institute, Patrick Garvey, shared with RNZ that the goal was to develop a non-lethal way to deter both feral and domestic cats.
While feral cats have been added to the Predator Free 2050 target species list, domestic cats continue to be beloved pets in many New Zealand households. The exact number of feral cats in New Zealand remains unknown, with estimates varying widely.
The inspiration for this research came from a successful trial in Canada in 2016, where the sound of dogs barking effectively deterred raccoons. Garvey’s team received funding years later to conduct similar tests targeting cats in New Zealand.
After conducting experiments, they found that feral cats were most repelled by human voices, while domestic cats were averse to the sound of other cats. The tests involved observing how cats reacted to different sounds when presented with food, with results showing varying levels of aversion based on the sound played.
Garvey emphasized that the sound cues could help in protecting colony breeding birds from feral cats near braided rivers. The researchers also collaborated with Auckland Council to deploy speakers in a reserve, although further research is needed to determine the practical effectiveness of this method.
Overall, Garvey sees this as a valuable tool to engage with the community and raise awareness about the potential harm of roaming cats. While it may not deter all cats, it can serve as a means to educate people and encourage responsible pet ownership.
