Killer Cats with Richard Dawkins of Federated Farmers

Feral cats are taking a toll on New Zealand farms by killing native wildlife and spreading disease. Toxoplasmosis is a parasite that needs a cat's intestines to complete its life cycle and contaminates the soil and water. It can infect people, livestock, even dolphins. With millions of feral cats roaming New Zealand, the threat is everywhere -- and our farmers are feeling the pain. What can we do about it?Joining the conversation is Richard Dawkins. He is the National Meet & Wool Chairman for the Federated Farmers and runs a sheep, beef, and viticulture farm in Marlborough.
