Where to wash tiger's head in animal centre (7)
I believe the answer is:
bathtub
'where to wash' is the definition.
I cannot understand how the rest of the clue works.
(Other definitions for bathtub that I've seen before include "Container for the body during ablutions" , "that may need a plug" , "Vessel in which one washes oneself" , "Object used for washing bodies" , "Vessel for ablutions" .)
