Some feel cat’s bowl, upended, creates barrier (8)
I believe the answer is:
obstacle
'barrier' is the definition.
(thesaurus)
'some feel cat's bowl upended' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'upended' shows that the letters should be reversed in order (in a down clue, letters go up).
'elcatsbo' can be found hidden inside 'feel cats bowl'.
'elcatsbo' written backwards gives 'OBSTACLE'.
'creates' acts as a link.
(Other definitions for obstacle that I've seen before include "Maybe let" , "difficulty" , "Thing blocking progress" , "Hindrance, obstruction" , "Anything that stands in the way" .)
