Russian tigress At the Berlin Zoo, Aurora gave birth to four tiger cubs seven weeks ago. The small big cats were now permitted to amuse the zoogoers and photographers by playing in the grass outside of their enclosure for a short period of time. The world’s biggest tiger is the Amur tiger. The creatures, also referred to as Siberian tigers, are situated in southeast Russia. There are currently only 450 of them in this area. Large-scale habitat degradation and hunting are to blame for this.
