Ten newborn Siberian tiger cubs at the Siberian Tiger Park in Hailin, northeast China's Heilongjiang Province, recently celebrated turning one month old with an adorable group photo session.

In recently released footage, the cubs look lively, active and irresistibly adorable.

According to the park, the 10 Siberian tiger cubs were born to three mother tigers. One of the mothers gave birth to quintuplets, but due to her limited ability to raise them all, the cubs are currently being hand-reared. The other two mothers gave birth to three and two cubs, respectively, and both litters are being nursed naturally by their mothers, with all in stable condition.

The peak natural breeding season for Siberian tigers runs from April to June each year, and cubs born during this period tend to have a higher survival rate.

Siberian tigers, mainly found in the cold regions of northeast China and Russia's Siberia, are listed as one of the world's top 10 most endangered animals.

The Siberian Tiger Park in Hailin is one of three tiger parks, all in the northeast, under the China Hengdaohezi Feline Breeding Center, the world's largest breeding center for Siberian tigers.

Since the center was established in 1986 – with just eight tigers at the time – the park has bred over 1,100 Siberian tigers.
