If that glowing sunshine out there isn't enough to melt your heart today, these lion cubs certainly will.

The litter of cubs were born in the Asian lion habitat in Dublin Zoo and feature in tonight's second episode of RTE series The Zoo. We'll also see how the zookeepers have to intervene to save one of the little tikes lives when he loses too much weight.

Look at them go in the clip below though, they are just too damn cute! Hard to believe they are going to grow up to be the terrifying Kings of the Jungle they become.

Catch The Zoo on Thursday's at 7pm on RTE1.
