The lion cubs born to much fanfare — and a live “cub” cam — at the National Zoo in 2010 are now teens on the cusp of adulthood. And with that comes eventual relocation from their home with the rest of their pride at the zoo, according to a news release sent Monday.

From the photo archives: KidsPost helps you keep track of the seven cubs to the zoo's lion yard.

The zoo has established a “Great Cats” team, a group of lion keepers who will observe the now-juvenile cubs’ behaviors and begin a gradual separation process “in order to minimize stress,” according to the release. It’s still too early to say where final destinations for each cub will be, but suffice it to say the quickly growing cats may need their space; the cubs range in weight from 216 to 272 pounds.

They grow up so fast, don’t they?
