Pet owners who fail to lock up their cats at night could face fines under a new curfew that is coming into effect in the outer-east.

It comes as Knox council tries to stop cats killing wildlife and spraying property.

The program will start from January 1 next year, with cats to be confined to their properties from sunrise to sunset.

The trial will run for a year before it’s reviewed by council officers with Councillor Nicole Seymour saying “Dogs aren’t allowed to go out at night, why should cats be allowed to roam?” 

However, another councillor Tony Holland said “a lot of rubbish”.

“I think it’s an old wives’ tale they (domestic cats) kill birds at night,” Cr Holland said.

It is expected local residents will be informed of the new rule before it is enforced.
