Catty remarks in converted stables (4)
I believe the answer is:
mews
I believe this clue is a double definition.
'catty remarks' is the first definition.
(sounds from cats)
'converted stables?' is the second definition.
(houses converted from old stables)
'in' acts as a link.
(Other definitions for mews that I've seen before include "House converted from stables" , "Street or yard with stables converted into houses" , "occupied dwellings that used to be stables" , "Houses, ex-stables" , "Calls from Tom" .)
