I'm willing to pay taxes to support such a catch/spay/neuter/vaccinate/release program. As I said, the only alternative (elaborating) is to shoot to kill, bag them and toss them in the trash.
I'll agree that adoption programs are good. My dog adopted me at one such program, actually at PetSmart (although the dogs were provided by LA Animal Control), and we are still together 14 years later. I'm glad they didn't bag and tag me!!!
I'm not a cat person although I think they too should be allowed to live.
