Sounds like family taking empty parking places for those younger Pride members (4,4)
I believe the answer is:
lion cubs
'younger pride members' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'sounds like family taking empty parking places for those' is the wordplay.
I cannot quite see how this works, but
'taking' could be 'on' (eg one taking drugs is 'on' drugs) and 'on' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lion cubs that I've seen before include "Babies of pride" , "Young carnivores" .)
