Feline catches right carriage (4)
I believe the answer is:
cart
'carriage' is the definition.
(thesaurus)
'feline catches right' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'catches' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'cat' going around 'r' is 'CART'.
(Other definitions for cart that I've seen before include "Old two-wheeled goods vehicle" , "Hump" , "Open wagon (to come after, not before, the horse)" , "Something not to be put in front of the horse" , "Primitive transport" .)
