Philanthropists' $1m pledge aims to double largest cat-free zone

Andrew and Jane Clifford promise to match donations in bid to stop feral cats

A $1m donation to the fight against feral cats could help to double the size of the world's largest cat-free sanctuary or help genetically neuter cats, conservationists say.

Sydney philanthropists Andrew and Jane Clifford have pledged to match every donation made to the Australian Wildlife Conservancy up to $1m before the end of the financial year, hoping to create a $2m fund to eradicate Australia's cat plague.
