Next time you come upon these animals, please contact:
http://www.sxmpaws.com/They also accept donations, as they help all homeless animals and feed them...often at their own expense.
They can care for them, round them up, feed them on-site, etc. And perhaps get them adopted to Forever Homes if they are healthy enough.
I brought home the most beautiful kitten last year. He's now my BIG cat! lol
