Beast in a bit of a hurry, feet sticking out! (6)
I believe the answer is:
ferret
But I can't explain it at all! Could you help me understand?
(Other definitions for ferret that I've seen before include "European polecat bred for hunting rabbits" , "Small fierce animal - good hunting rabbits" , "Search around - domesticated polecat" , "Animal used to catch rabbits" , "Small weasel good at hunting rabbits" .)
