Ordered cab to follow black feline (6)
I believe the answer is:
bobcat
'feline' is the definition.
(bobcat is a kind of feline)
'ordered cab to follow black' is the wordplay.
'ordered' indicates an anagram.
'follow' is a charade indicator (letters next to each other).
'black' becomes 'b' (as in pencil classifications).
'cab'+'to'='cabto'
'cabto' is an anagram of 'obcat'.
'obcat' after 'b' is 'BOBCAT'.
(Other definitions for bobcat that I've seen before include "North American lynx" , "Kind of lynx" , "Small N American lynx" , "North American feline" , "Relation of the lynx" .)
