Cats are being blamed for the spread of native wildlife-killing toxoplasmosis as calls for urgent action to tackle the infection are being called.

As feral cat populations in Tasmania have grown, toxo as it's known, has taken a massive toll on local wildlife, spreading through the urine and faeces of cats to mammals, with humans being susceptible.

Minister for Primary Industries and Water Sarah Courtney said amendments to the 2017 Cat Management Act were "currently being drafted" and were "expected to be tabled in Parliament in the near future.”

But Peter McGlone, a member of one of the groups that worked with government to develop the new cat management plan for Tasmania, says the plan has been “gathering dust since it was finished last year” and can’t believe the government’s slow pace at implementing it.
