Cat owners living in some northeastern suburbs could soon be forced to walk their cats on leashes, if new bylaws are passed by Campbelltown City Council.

The proposed bylaws would also see a council-wide cat curfew implemented between 9pm and 7am.

The move is an attempt to reduce the impact of domestic cats on native wildlife, although cat advocates argue that it would do little to prevent problems caused by feral and stray cats.

Cat advocacy groups argue that sterilisation is a better approach to prevent the widespread impact on wildlife.

If introduced, cats would be confined to owners’ houses, unless exercising them on a leash in public. Domestic cats would also need to be registered and wearing collars with tags.

The news comes after other Adelaide councils either moved to introduce stricter cat control measures.

City of Marion Council has sought to introduce a curfew on domestic cats, an idea which drew criticism from Queen guitarist Brian May.
