Animal in tree escaping from trap (3)
I believe the answer is:
ewe
'animal' is the definition.
(female sheep)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for ewe that I've seen before include "Scottish loch" , "Palindrome for a female sheep" , "One needing pastoral care" , "Dam of a sheep" , "Female animal" .)
