Wild lion and tiger lurking (9)
I believe the answer is:
loitering
'lurking' is the definition.
('loiter' can be a synonym of 'lurk')
'wild lion and tiger' is the wordplay.
'wild' is an anagram indicator.
'and' says to put letters next to each other (I've seen this in other clues).
'lion' put after 'tiger' is 'tigerlion'.
'tigerlion' anagrammed gives 'LOITERING'.
(Other definitions for loitering that I've seen before include "Hanging around or lurking" , "Lingering" .)
