Ivor invested in Carne with endless types of Fat Cats, for example (10)
I believe the answer is:
carnivores
'cats for example' is the definition.
(cat is a kind of carnivore)
'ivor invested in carne with endless types of' is the wordplay.
'invested in' means one lot of letters goes inside another.
'with endless types of' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'ivor' inserted inside 'carne' is 'carnivore'.
'carnivore'+'s'='CARNIVORES'
'fat' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for carnivores that I've seen before include "who won't touch Greens?" , "Meat-eaters" .)
