One-year-old Siberian tiger cubs get their claws out as they square up for boxing match
The boisterous brothers were showing off their fighting prowess

THESE tiger cubs are already earning their stripes by showing off their paw-some fighting skills.
The two Siberian cubs are only a year old but they certainly pack a powerful punch as they take turns hitting each other over the head.
Thankfully the boisterous brothers were just play-fighting as they brawled in Nuremberg, Germany.
In a series of stunning shots, the cubs take turns to bat each other in the head as they try to one-up the other.
At one point, one of the brothers leaps out of the pool and towers over his sibling.
He uses the opportunity to attack the other cub from above - causing him to stumble and fall.
But the beaten brother rises to strike his sibling in the face once more.
The incredible photos were taken by local technical author and amateur photographer Peter Weimann.
Siberian tigers are the largest cat in the world when fully grown - measuring around 11ft in length and weighing up to 320kg.
