My wife and I contribute to a fund at our no-kill animal rescue unit that helps trap feral cats at apartment complexes throughout the city. The apartment owners trap them, especially with their kittens, and bring them to us..We spay/neuter them and socialize the kittens. The adults which cannot be socialized are sent back to the apartments where they were found. Many times it is the only home they know as they were abandoned there by people moving. The apartment owners have their maintenance people get cat food from us and then feed them there. A lot of new apartment lessee's also feed them. The kittens are adopted out to good homes. We even have people that goes to the kittys prospective homes to inspect it and make sure it's ok.
