Pull cat's tail after a stretch (7)
I believe the answer is:
attract
'pull' is the definition.
(I know that pull can be written as attract)
'cat's tail after a stretch' is the wordplay.
'tail' indicates one should take the final letters.
'after' is a charade indicator (letters next to each other).
'stretch' becomes 'tract' (a tract is a stretch of land).
The final letter of 'cat' is 't'.
't' put after 'a' is 'at'.
'at'+'tract'='ATTRACT'
(Other definitions for attract that I've seen before include "Allure" , "Draw, pull" , "Lure" , "Bring in" , "Draw to oneself" .)
