The only flightless perching bird known in New Zealand, the Stephens Island Wren, was discovered and soon after eliminated by a lighthouse keeper's cat in the late 1800s. Just 17 specimens of the little bird were ever collected. It doesn't matter how much your cat is fed at home, he or she still loves to hunt. You just don't know what they are up to when you aren't watching. So what should you do? * Have your cat neutered or spayed so they can't produce unwanted kittens * Keep your cat well fed and have moving toys for it to play with, so it is less inclined to chase birds etc. * Keep your cat indoors overnight so nocturnal insects and lizards have free reign of your garden. * Put a bell on its collar so it can't sneak up on birds. * Don't dump unwanted kittens and cats - either give them to the SPCA or ask a vet to put them down humanely.
