There’s snow time like play time! In winter Siberian tigers forego their normal nocturnal lifestyle and use what little daylight there is to hunt and play; a mother must increase her hunting success by 50 per cent to feed a litter of two or three cubs. Deer, wild boar and even bears are targeted by these huge carnivores. Extra: Cubs are born blind and helpless but they grow quickly, increasing their body weight four times in just one month
