Cautious repairs to fur and lace (7)
I believe the answer is:
careful
'cautious' is the definition.
(synonyms)
'repairs to fur and lace' is the wordplay.
'repairs' indicates anagramming the letters (I've seen 'repair' mean this (letters are fixed or repaired)).
'and' says to put letters next to each other.
'fur' after 'lace' is 'lacefur'.
'lacefur' anagrammed gives 'CAREFUL'.
(Other definitions for careful that I've seen before include "Diligent" , "Watch it!" , "Painstaking" , "Thrifty" , "'Prudent, cautious (7)'" .)
