By no means the leading set of equipment for a new pet (6)
I believe the answer is:
kitten
'pet' is the definition.
(I know that kitten is a type of house cat)
'by no means the leading set of equipment for a new' is the wordplay.
'by no means' becomes 'te' (I can't explain this - if you can you should believe this answer much more).
'the leading' is a charade indicator (letters next to each other).
'set of equipment' becomes 'kit' (I've seen this before).
'for' is a charade indicator (letters next to each other).
'a new' becomes 'n' (common abbreviation eg NT for New Testament).
'te' put after 'kit' is 'kitte'.
'kitte'+'n'='KITTEN'
Can you help me to learn more?
(Other definitions for kitten that I've seen before include "found in litter" , "Little feline" , "Beatrix Potter's Tom, say" , "Mini-mog?" , "Young of a beaver" .)
