Level with a wild animal, runs into it (7)
I believe the answer is:
abreast
'level with' is the definition.
(I've seen this before)
'a wild animal runs into it' is the wordplay.
'wild animal' becomes 'beast' (I've seen this in another clue).
'runs' becomes 'r' (cricket abbreviation).
'into it' is an insertion indicator.
'beast' going around 'r' is 'breast'.
'a'+'breast'='ABREAST'
(Other definitions for abreast that I've seen before include "Familiar" , "Side by side; keeping pace" , "shoulder to shoulder" , "acquainted" , "Side by side - in the picture" .)
