Hi June,
Could you raise a petition? And get all of your neighbours to sign it. The petition could explain your objectives and the rational behind the TNR program which you are implementing, perhaps referencing other such TNR programs operating in other parts of the world...
Once you have a petition of support from your neighbours you could see if any news papers are interested in your story, again another opportunity to pitch the TNR program as a progressive means of humanly addressing the stray population. If you could get the DBKL to sign the petition too, on the grounds of TNR, then extra kudos!
At this point you might get your local MP interested,
I don't know if this strategy would work here in Malaysia though, but...
Good luck!
