Puss let out farm animals (6)
I believe the answer is:
cattle
'farm animals' is the definition.
(I've seen this before)
'puss let out' is the wordplay.
'puss' becomes 'cat' (I've seen this in other clues).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'let' anagrammed gives 'tle'.
'cat'+'tle'='CATTLE'
(Other definitions for cattle that I've seen before include "Where it naturally lies (Latin)" , "feature of 21/23 [NATIVITY SCENE]" , "New York district" , "Animals raised for meat" , "Stock farm" .)
