Fox and wolf beginning to hunt excessively (2,5)

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

'fox and wolf beginning to hunt' is the wordplay.
'fox' becomes 'tod' (historic term).
'and' is a charade indicator (letters next to each other).
'wolf' becomes 'eat' (wolf can informally mean to eat or consume).
'beginning to' suggests taking the first letters.
The initial letter of 'hunt' is 'h'.
'tod'+'eat'+'h'='TO DEATH'
