Beasts: rule-breakers, we hear? (8)
I believe the answer is:
cheetahs
'beasts' is the definition.
The answer and definition can be both animals as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for cheetahs that I've seen before include "Swift, long-legged cats" , "Fastest mammals on land" , "they' re spotted making rapid progress" , "The aches one gets from big cats" , "fast runners" .)
