About time for puss (3)
I believe the answer is:
cat
'puss' is the definition.
(I've seen this in other clues)
'about time' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa'**).
'time' becomes 't'.
'ca'+'t'='CAT'
'for' is the link.
(Other definitions for cat that I've seen before include "Animal (domesticated or wild)" , "Animal - one with nine tails!" , "See 23" , "Grimalkin" , "Animal; converter; boat" .)
