Prince George, Princess Charlotte And Prince Louis Quiz David Attenborough In Adorable Video

You can watch it below:

In the clip, George, Charlotte and Louis each ask Sir David, 94, a question - and it's the first time the public has ever heard the Cambridge kids speak on camera.

Quizzing the historian on the topic of extinct animals, Prince George, 7, is up first and asks David: "Hello David Attenborough! What animal do you think will become extinct next?"

And David is quick to respond, explaining to George that he hopes there won't be any.

"Well let's hope there won't be any because there are lots of things we can do when animals are in danger of extinction - we can protect them," says David.

"About 40 years ago I was with some mountain gorillas in the centre of Africa. Mountain gorillas were then very, very rare, there were only 250 of them left.

"We showed pictures of them on television around the world and people thought how terrible it would be if these became extinct. So they subscribed lots of money and lots of people came to help and now there are over 1,000 of them."

Next up, it's five-year-old Princess Charlotte's turn, and she asks the most adorable question.

"Hello David Attenborough! I like spiders, do you like spiders too?"

Sir David loves all creatures great and small as we know, and replied explaining: "I love spiders, I'm so glad you like them!

"I think they're wonderful things. Why is it that people are so frightened of them? I think it's because they have eight legs - much more than us.

"... But spiders are so clever. Have you ever watched one trying to build its web? That is extraordinary."

Last but not least, little Prince Louis - aged two - took a huge breath and asked the historian: "What animal do you like?"

And Sir David explained that if he had to choose, he would go for a monkey - but if it came down to a pet the kids could have at home, he'd say a puppy.

"I think I like monkeys best, because they're such fun - they can jump all over the place and they're so funny. And I like them a lot.

"Mind you you can't have monkeys sitting around the home, because that's not where they live - they live out in the forest.

"So what you can have at home that you like? Well, which would you choose, a puppy or a kitten? I think I'd go for a puppy."

Hmmm, we wonder if there could be a new, four-legged addition to the Cambridge household at some point soon?!
