Animals causing a small stir? (6)
I believe the answer is:
llamas
'animals' is the definition.
(llama is a type of animal)
'a small stir?' is the wordplay.
'stir?' indicates anagramming the letters (I've seen 'stirring' mean this).
'a'+'small'='asmall'
'asmall' anagrammed gives 'LLAMAS'.
'causing' acts as a link.
(Other definitions for llamas that I've seen before include "Andean pack animals" , "domesticated guanacos" , "South American animals like the camel" , "South American animals related to camels but humpless" , "Sal and Mal for the animals" .)
