A male white lion by the name Ivory and a female white tiger by the name Saraswati are the proud parents of a litter of four cubs that are not only the first of their kind, but also the world's rarest big cats.

The baby white ligers – a liger is the offspring of a lion and a tiger – were born at the Myrtle Beach Safari in South Carolina, US about six weeks ago, Daily Mail reports.

They are named Yeti, Odlin, Sampson and Apollo, and weigh about 15 lbs (6.8 kilograms) each. According to their caretakers, they nurse very well and currently gain about 1 pound (0.45 kilograms) on a daily basis.

Hence, it is said that, when they become adults, they might just be the biggest cats in the world.

Of the four male cubs, Yeti is the one most likely to set a new world record in terms of size.

“All the cubs grow so quickly, but Yeti is already so much bigger,” says Dr. Bhagavan Antle.

“I skip a day seeing them and it looks like they’ve doubled in size. It’s like someone’s blowing them up with a tyre pump,” he adds.

Folks at the Myrtle Beach Safari expect that, by the time they turn two, the cubs will have grown to weigh at least 750 lbs (340.2 kilograms) and measure 10 feet (about 3 meters) in height.

In two more years, they could grow to weigh an impressive 900 lbs (408.2 kilograms), maybe more.
