For this animal, a record's a piece of cake! (6)
I believe the answer is:
alpaca
'for this animal' is the definition.
(South American animal)
'a record's a piece of cake' is the wordplay.
'record' becomes 'lp' (LP is an example).
'piece of cake' becomes 'ca' (I can't justify this - if you can you should believe this answer much more).
'a'+'lp'+'a'+'ca'='ALPACA'
Can you help me to learn more?
(Other definitions for alpaca that I've seen before include "Fabric from wool of S American llama" , "Silky fleece of a lama" , "Llama-like creature" , "creature of the Andes" , "Llama relation" .)
