In China, three playful white Bengal tiger cubs are charming visitors as they clamber around their enclosure at a zoo in Kunming.

"The oldest one -- the largest -- is very naughty and has a real appetite and the youngest is like a baby, she's gentle.

The cubs' busy mother is getting a helping hand keeping her youngsters from getting hungry, with keepers always ready to step in with a bottle.

The tigers' white fur is a genetic variation of the common orange Bengal tiger.

There are currently more than 2,500 Bengal tigers outside captivity, most of them in India, according to conservation group World Wildlife Fund. A competition is being held to name the three newborns, with final names chosen at the end of October.
