Finding piece of wood to entertain pet at home (8)
I believe the answer is:
Here is my best explanation:
'finding' is the definition.
(locating is a kind of finding)
'piece of wood to entertain pet at home' is the subsidiary indication.
'piece of wood' becomes 'log'.
'to entertain' means one lot of letters goes inside another.
'pet' becomes 'cat' (I've seen this in other clues).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'log' going around 'catin' is 'locating'.
(Other definitions for locating that I've seen before include "Coming across" and "Finding".)
