Hey, paws off my ball! Un-bearably cute twin polar bears celebrate their 100th-day birthday in China



They were born weighing less than a bag of sugar and not expected to survive.

But now, on their 100th-day birthday these twin polar bears are thriving and finding time to play a ball game or two.

They were born on March 5 and, to give them the best chance of survival, keepers at Tianjin Haichang Ocean World in northern China placed them into incubators.

Since then four keepers have been attending to their needs around the clock.



Keeper, Sun Qinbao, said: 'They were so tiny at birth. The elder sister was 497grams and the younger one was 560grams.



'In the first few days their eyes were still not open and they just ate and slept.'
