Weight given for snow leopard (5)
I believe the answer is:
ounce
This clue is a double definition.
'weight' is the first definition.
(unit of weight)
'for snow leopard' is the second definition.
(ounce is an alternative name for the snow leopard)
'given' is the link.
(Other definitions for ounce that I've seen before include "Imperial unit of weight" , "weight? Surely not" , "Approx. twenty-eight gm" , "Enough to tip the scales" , "one of a number in the pound" .)
