Enjoyment found in cathouse as ever (4)
I believe the answer is:
ease
'enjoyment' is the definition.
(thesaurus)
'in cathouse as ever' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EASE' is hidden within 'cathouse as ever'.
'found' is the link.
(Other definitions for ease that I've seen before include "Comfort; simplicity" , "Effortlessness" , "Freedom from worry" , "Freedom from worries" , "Comfort; facility" .)
