Bedding for the young (6)
I believe the answer is:
litter
I believe this is a double definition.
'bedding' is the first definition.
(I know this)
'the young' is the second definition.
(thesaurus)
'for' acts as a link.
(Other definitions for litter that I've seen before include "Refuse - to give birth" , "Cubs" , "Sow's young" , "Clean up the canine offspring?" , "Carelessly-dropped rubbish" .)
