Like most of Christchurch's human residents, exotic animals in the city are also proving resilient in the face of ongoing aftershocks in the region.
Orana Wildlife Park chief executive Lynn Anderson said last Friday's two large aftershocks showed animals have adjusted to the quakes which have rattled the city since September 4.
"On Friday, one lionesss simply twitched her ear when the big one hit - she didn't even move. Even the previously flighty antelope species can be grazing again within minutes of a large shake."
Ms Anderson said the cheetah have gone from "freaking out and running around" after the September and February 22 quakes, to hardly batting an eyelid.
White rhino, the giraffes and the emu had also become more used to the ground moving violently beneath them.
