I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">animal's trail</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for spoor that I've seen before include "Trace" , "Animal track or scent" , "24 [TRAIL]" , "Animal's track/scent" , "Track of wild animal" .)
