Made pets nervous and livestock panic (8)
I believe the answer is:
stampede
'livestock panic' is the definition.
'stampede' can be an answer for 'panic' (thesaurus). I'm not sure about the 'livestock' bit.
'made pets nervous' is the wordplay.
'nervous' is an anagram indicator (letters get shaken up).
'made'+'pets'='madepets'
'madepets' anagrammed gives 'STAMPEDE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for stampede that I've seen before include "unstable flight" , "Sudden rush of frightened animals" , "Rampage" , "Disorderly rush" , "uncontrolled flight" .)
