Watch closely but missing old hare (4)
I believe the answer is:
scut
'hare' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for scut that I've seen before include "Short tail of hare" , "Short erect tail" , "Deer's tail" , "Short tail, such as rabbit's" , "Short tail of rabbit, deer etc" .)
