Cat makes attack following pressure (5)
I believe the answer is:
ounce
'cat' is the definition.
(ounce can mean a snow leopard)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ounce that I've seen before include "Light weight coming in on cue" , "Imperial unit of weight" , "Small unit of weight" , "28.3495 grammes" , "small portion" .)
