In Kent, oddly, it’s a young animal (6)
I believe the answer is:
kitten
'a young animal' is the definition.
(I've seen this before)
'in kent oddly it's' is the wordplay.
'in' is an insertion indicator.
'oddly' indicates anagramming the letters (letters in an odd order).
'kent' with letters rearranged gives 'kten'.
'kten' going around 'it' is 'KITTEN'.
(Other definitions for kitten that I've seen before include "youngster" , "Young rabbit" , "Mini-mog?" , "Baby cat" , "Young feline animal" .)
