Gareth Morgan is pitching his latest conservation project at schools in the hope children pressure their parents into cat control.
The move has alarmed a Parent-Teacher group which says it could create friction with some parents.
The project, Enhancing the Halo, is a web-based campaign to be launched tomorrow that aims to increase predator control around Wellington by creating what Morgan describes as "the most intensive trap-line in the country".
The website teaches "Halo households" about conservation techniques, such as planting native bush and trees and trapping pests on their property.
Dr Morgan counted cats as pests alongside rats, possums and mice.
