Exotic pet (6)
I believe the answer is:
iguana
'exotic pet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iguana that I've seen before include "Type of lizard" , "Creature" , "Large tree-climbing lizard of tropical America" , "The Night of the ---, (T. Williams)" , "Something like a monitor" .)
