The mission to save the world's rarest cat
Fifty years ago, the Iberian lynx was pretty common in parts of Spain, now they're really hard to spot.
They've come so close to extinction after being hunted and having their habitats destroyed, that at one point there were just 150 left in the wild.
Now conservationists are so worried, they've put almost all of the remaining wild cats into captivity - something they'd never normally do.
But they're really desperate for the animals to breed away from danger.
So far, it seems to be working as eight cubs have been born this year.
The next challenge is to release them back into the wild, which could start next year.
