I'm a little stuck... Click here to teach me more about this clue!

'the cat' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for lash that I've seen before include "Whip; securely fasten" , "Strike with a whip" , "Whip; attack verbally" , "over the eye" , "Sweep" .)

I've seen this clue in the Evening Standard.
