I suggest calling animal control and checking to see if there is a cat rescue organization.

There's a small cat rescue operation in my area committed to trapping alley cats. They are spade and vaccinated (rabies can be a problem with unvaccinated feral cats). If possible they are adopted out but many are released back into their alley environments (where residents often feed them).

A friend and I had our dogs in the park when a 6 week or so old kitty came running across the road and was nearly snagged by a German Shepherd. That's when we learned about the cat rescue.

We bathed that kitten (oh my!), had her vaccinated, de-flead and de-wormed and then placed her with a good home. We also worked with the cat rescue to place, bait and monitor a cage trap to catch littermates and the mama. A cage similar to this:

We caught and were able to place another kitten (who hit the jackpot and now holidays on Nantucket with her dog and cat housemates).
