Attack small animals (5)

I believe the answer is:

goats

'animals' is the definition.
The answer is an example.

'attack small' is the wordplay.
'attack' becomes 'goat' (go at).
'small' becomes 's' (abbreviation - e.g. clothes size).
'goat'+'s'='GOATS'

(Another definition for goats that I've seen is " ruminants".)

I've seen this clue in The Telegraph.
