Three adventurous meerkat pups are finding their feet, after emerging from their den at the National Zoo and Aquarium in Canberra.

Born in August, the pups weigh just 150 grams and until now have been keeping a low profile, cared for by parents Sekai and Sergai inside the burrow.

But now the trio is ready to make its public debut as the first meerkat pups to ever go on display at the zoo.

Operations manager Renee Osterloh has the enviable job of watching the adorable pups grow up.

She said the other meerkats in the family had all been babysitting the youngsters.

"It's wonderful to watch them explore their new surroundings and they're always learning from their mum, dad and older siblings," she said.

Now that they are four weeks old, they have begun travelling with their group to forage - they will be fed by the helpers for the first three months until they learn to catch their own food.

For now, it is still too soon to tell the pups' genders.

"We haven't named them as yet. In a couple of weeks keepers will take a closer look at the new arrivals and we will determine their gender," Ms Osterloh said.

The public will get the chance to name the pups once it is known whether they are male or female.
