Carry an animal (4)
I believe the answer is:
bear
I believe this clue is a double definition.
'carry' is the first definition.
(bear can mean to transport or carry)
'an animal' is the second definition.
(I know that bear is a type of animal)
(Other definitions for bear that I've seen before include "See 13 across" , "Falling market for large furry animal" , "Tolerate; animal" , "Massive mammal" , "Support, large mammal" .)
