Four new ligers have just joined the world, and it’s all thanks to this beautiful pair — a white lion and a white tiger.

No, they're not some kind of otherworldly fairytale creature: This is the liger, and it's very, very real.

The new cubs are Yeti, Odlin, Sampson, and Apolo.

Their birth makes them the rarest big cats on the planet. At six weeks old, they already weigh about 15 pounds — and they gain about a pound per day.

It’s hard to believe that these little cubs could actually grow to cats this size.

There are only around 300 white lions and 1,200 white tigers left in the world, so the cubs’ father, Ivory and mother, Saraswati, are extremely rare as well — not to mention massive.

There are about 1,000 ligers in the world, but there’s one thing about these cups that set them apart.

None of the other ligers are white like these little guys.

According to the keepers, each of the ligers has its own distinct personality.

Apollo is the smallest, who his owners say behaves more like a house kitten, demanding to be cuddled all the time.

Yeti, another cub, always wants to be the center of attention.

The cubs’ extended family is pretty impressive as well.

The cubs’ uncle, Hercules, is officially the world’s largest cat at 922 lbs and 131 inches long and is featured in the Guinness Book of World Records. The keepers at the zoo say that it’s possible for one of the cubs to reach this size, too.

The cubs' extended family is pretty impressive as well.

Now, the zookeepers and the cubs are just enjoying all the attention. “We’ve had everyone from Congress to people of all walks of life come,” one keeper said in an interview. “They are honestly such an incredibly unique sight.”
