FR Bearing in mind that most of what I know about NZ's fauna comes from Last Chance to See, by Douglas Adams, which I read a long time ago: NZ is something of a special case, ecologically speaking. From what I remember, the main point was that the species of islands in general are more specialised than those of continents. They're not as tough, to put it crudely. There's a flightless parrot, for instance, that lays its eggs on the ground. And these parrots mate only rarely, and produce few eggs. (In fact one per season, IIRC.) No way would such a species last even in the UK, let alone North America. Domestic cats and rats (no matter how cute - and even rats can be cute), on the other hand, are very 'tough' indeed. They can live pretty much anywhere. Part of their toughness lies in their ability to get hold of and eat very wide ranges of foods. They also breed easily. That's the problem here, I think. Letting a cat roam free in NZ seems to be much like letting an armed, serial-killing psycho wander around a cosy Devon village.
