'silky beast' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'article on farm animal biting motorists' is the wordplay.
'article on' becomes 'an' (indefinite article. I am not sure about the 'on' bit.).
'farm animal' becomes 'goat' (I've seen this in another clue).
'biting' means one lot of letters goes inside another (some letters bite or swallow others).
'motorists' becomes 'rac' (short for Royal Automobile Club).
'goat' going around 'rac' is 'goracat'.
'an'+'goracat'='ANGORA CAT'
