Taronga Zoological Park in Sydney, Australia, just welcomed two meerkat babies into their zoo. The little meerkats are so small that both of them fit in their keeper's hands at once. They were born on Jan. 7, weighing only a few grams at the time, and now they weigh 120 grams. While that's only 0.2 lbs, it shows that they're developing quickly and healthily, reported The Telegraph.

The zoo isn't sure of the genders of the meerkats yet, but they've got a hunch. "They may be young, but they're already showing signs of their own little personalities. Our male is the bigger of the two and he's more adventurous and inquisitive, while the female is quieter and prefers to stay close to mum," said Courtney Mahoney, the newborn meerkats' keeper, according to the Taronga Zoo's website. "They were initially a little wary of this big new world outside, but with a bit of encouragement from mum and dad they started to explore."

Nairobi, the mom, and Maputo, the dad, are doing a great job at raising their young. "This is all new for them and they learn by observing their mum and dad, so we're very lucky that Nairobi and Maputo are proving to be fantastic and attentive first-time parents. Nairobi is letting the pups suckle and grooming them at the right times and Maputo protects them, huddles over them and curls up with them at night," Mahoney said in the press release.

The photos that the zoo released of the babies have gotten worldwide attention. "These little faces belong to the first Meerkat pups born at Taronga in nearly seven years! The two pups are starting to venture out of their nest box for short periods, as they are slowly introduced to the outside world under the watchful eyes of their parents and keepers," the Zoo said on their Facebook page.
