Earlier this year, the National Zoo’s lion Nababiep gave birth to two new lion cubs, her third litter and the fourth from the cubs’ father, Luke.

A few weeks ago, Zoo officials said that “Naba allowed her eight-week-old cubs to meet their aunt Shera at a mesh ‘howdy’ door,” and last week the cubs finally met their half-siblings. And because it’s Friday and the weather is nice and everything is generally good for now, the National Zoo has released this adorable video of the half-siblings meeting for the first time. Spoiler alert: adorable battles ensue. Happy Friday, you guys.
