And... Pounce!
Like our experience with the cheetah, we had searched the area around Ndutu looking for these lion cubs without success until our last day in the area.  Our patience paid off on this day, as we found 2 cubs that were very active. 

Here we see one of them as it pounced onto its mom... but mom was smarter and just pulled him down and gave him a good tongue bath!
