Cross cat (5)
I believe the answer is:
tigon
I believe this clue is a double definition.
'cross' is the first definition.
(I've seen this before)
'cat' is the second definition.
(offspring of a lion and a tiger)
(Other definitions for tigon that I've seen before include "Big hybrid of the cat family" , "Tiger-lion hybrid" , "cat cross" , "Cross between two big cats" , "Animal" .)
