Yes, the poet has used exaggerations such as the cat's defiance of gravity and it being called a 'monster of depravity' and a 'fiend' in order to enhance the mystery surrounding the cat. Since the cat is shown to be super-fast as nobody from the Scotland Yard to the flying squad can catch it on the scene of crime These exaggerations have been used by Eliot to lay stress on this monstrous as well as surprising and mysterious nature of Macavity. Examples:
(i) 'He's the bafflement of Scotland Yard, the Flying Squad's despair'.
(ii) 'He breaks the law of gravity'.
(iii) 'His powers of levitation would make a fakir stare.
(iv) 'He's a fiend in feline shape, a monster of depravity.
(iv) 'He is the Hidden paw'
