In a short time viceroy is taking in English cats (7)
I believe the answer is:
moggies
'cats' is the definition.
I know nothing about this answer so I can't tell whether this works.
'in a short time viceroy is taking in english' is the wordplay.
I cannot really understand how this works, but
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'is' is found in the answer.
'short time' could be 'mo' (as in 'just a mo') and 'mo' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for moggies that I've seen is " Cats (sl.)".)
