Called out plot to capture animal shelter (6)
I believe the answer is:
barked
'called out' is the definition.
(bark can mean to shout)
'plot to capture animal shelter' is the wordplay.
'plot' becomes 'bed' (bed is a kind of plot).
'to capture' means one lot of letters goes inside another.
'animal shelter' becomes 'ark' (ship which shelters animals in the Bible).
'bed' enclosing 'ark' is 'BARKED'.
(Other definitions for barked that I've seen before include "Sounded like a dog" , "Made sounds like a dog" .)
