Rub the wrong way and seem to worry the cat (7)
I believe the answer is:
burmese
'the cat' is the definition.
(I've seen this before)
'rub the wrong way and seem to worry' is the wordplay.
'the wrong way' is a reversal indicator.
'and' is a charade indicator (letters next to each other).
'to worry' indicates an anagram.
'rub' backwards is 'bur'.
'seem' anagrammed gives 'mese'.
'bur'+'mese'='BURMESE'
(Other definitions for burmese that I've seen before include "Native to Myanmar" , "Asians" , "Breed of cat" .)
