Sounds like family taking empty parking places for those younger members of Pride (4,4)
I believe the answer is:
lion cubs
'sounds' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for lion cubs that I've seen before include "Babies of pride" , "Young carnivores" .)
