Inventory of cattle? (5)
I believe the answer is:
stock
I believe this clue is a double definition.
'inventory' is the first definition.
(I know that inventory can be written as stock)
'cattle?' is the second definition.
(I've seen this before)
'of' acts as a link.
(Other definitions for stock that I've seen before include "Repute" , "Neck adornment" , "Wares" , "raw material" , "Neckwear; supply" .)
