Does your area have catch, spat/neuter, and release programs for strays?

Usually you get surprise kittens when either someone's unfixed animal gets out and gets pregnant/gets another cat pregnant, or when kittens are dumped because some people aren't good, or unfixed strays get pregnant and have babies.

Some areas may have predators that would deter cats (humans, coyotes, large snakes, alligators, crocodiles, puma/mountain lions etc). Some areas aren't hospitable (weather wise) to strays.
