New Zealand had 11 bird species extinct due the introduction of non native predator species for which cats take the biggest toll.Many cats have no owner in New Zealand and are considered as feral.But New Zealand has also many cats who have a home but being allowed to roam free and they also add to the killing.All countries should look at New Zealand and learn from their past in order not to make the same mistakes.
Not native animal species should be removed from every country and non native animal species contained and controlled in numbers. Both can be done and should be done because our animals species worldwide dwindle down in rapid numbers and we must do whatever we can to slow this process down or to stop it.
Every pet animal has to be contained and it doesn’t make sense why cats should be the exception as they from all the standard pet animals wreak the most havoc in biodiversity because they are the most skilled hunters and no cat owner who says their pet doesn’t hunt is observing their cat 24/7 aren’t they? ???! Any cat kills and if a cat gets a adult bird in breeding season a whole family will die because the chicks will starve to death!
I grew up with cat’s and their were always in a self constructed catio or kept indoors and cat keepers not doing that is based on convenience, laziness and nit wanting to take responsibility as a animal keeper.Pet animals come with great responsibility and one of them is the prevention to do whatever neccessary to prevent other native forms being killed or even driven into extinction.

THE DIET OF FERAL CATS ON RAOUL ISLAND, KERMADEC GROUP
“When cats were introduced last century the introduced kiore (Rattus exulans) was the only mammalian prey though many birds were available. Land birds present then included the Kermadec red-crowned parakeet, an un-described pigeon, tui, and sacred kingfisher; seabirds included at least five species of petrels and three species of terns (Merton, 1970).
Norway rats(Rattus norvegicus) were introduced in 1921. Now cats and rats are common, the local pigeon is extinct, parakeets are represented only by stragglers from the nearby Herald Islets, and the only common seabird is the colonial-nesting sooty tern(Sterna fuscata) which may be threatened by cats and rats (Taylor, 1979)”

Primary cause of extinction; Cats, pigs and human hunting.
