Cottonflower

I recently moved to this neighborhood less than a month ago. Just last week I saw 4 kittens running around the green wash by 172nd and Mohave.  Does anyone know if there are feeders in the neighborhood? I would like to get these cats trapped and fixed so they do not multiply.  Please respond if you have any info and if you'd like to help with the TNR.  (TNR is the most sucessful way to control stray cat population. It stands for Trap Neuter Return and it is a humane way. Please google for more info).
