A local council on the south-west fringe of Sydney is lobbying the State Government to limit the number of cats non-breeders can own in New South Wales.
Wollondilly councillor Simon Landow is leading the push to impose the statewide cat cap, which he believes will create "an equal playing field between dogs and cats".
Mr Landow said while the limit would ultimately be determined by the Government, he believed owners should have no more than six felines unless they're registered breeders.
Wollondilly Council's proposal was motivated to pursue the changes to protect native species, millions of which were killed each year by cats, he said.
