Fake keepers at zoo houses (6)

I believe the answer is:

ersatz

'fake' is the definition.
(I've seen this before)

'keepers at zoo houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'ERSATZ' is hidden in the letters of 'keepers at zoo'.

(Other definitions for ersatz that I've seen before include "Inferior substitute" , "'Artificial, not genuine (6)'" , "unnatural" , "Imitation or substitute, from German" , "Made in imitation - in Germany" .)

I've seen this clue in The Telegraph.
