Tracked down and slaughtered another rat (3,2,5)

I believe the answer is:

ran to earth

'tracked down' is the definition.
(I've seen this in another clue)

'slaughtered another rat' is the wordplay.
'slaughtered' indicates anagramming the letters.
'another'+'rat'='anotherrat'
'anotherrat' is an anagram of 'RAN TO EARTH'.

'and' acts as a link.

I've seen this clue in The Guardian.
