I won't deny there are irresponsible cat owners. However, I'm not one of them. I always tried my damnedest to make sure our animals stayed in the yard, but it wasn't always possible. I had to resort to some creative fencing to keep my Siamese from wandering (after a particularly exhausting chase around the neighborhood at 3 a.m. one summer night). She was much more manageable after being spayed.I simply don't have a better idea that is both feasible and actually qualifies as being half concerned about the environment that doesn't involve the mass culling of unattended outdoor domestic cats. Unfair to the cats? Well, insofar as you can be unfair to a cat, sure - it is. I'm sure some people will value feral cats and their ability to let their own cats wander about more highly than conservation or native bird/mammal populations.
As for my dogs, we had one that loved to take himself for walks. Before he was even legally ours (we were sitting for him for my great-uncle), some idiot visitor of ours let him out without letting us know. It took a week to find him - he'd been hauled in to the pound after making it halfway across town. We caught a break on the fines because we'd been frantically calling the pound and SPCA, actively looking for him, and he had a collar and license - just not a local one, since my great-uncle was from another province. After we got him back, we had him groomed, and my grandmother fell in love with him (it was mutual). When my great-uncle returned, he was very displeased to hear what had happened, and my grandmother noted that the dog was an inconvenience to his legal owner, she and the dog had become attached, and could she have him? It took him all of about 30 seconds to think it over and say, "Well, okay." After that, we got him neutered, a current, local license, and then I started obedience training and regular walks with him. He did get out a few times after that, but would finally come when called.
My point is that you really shouldn't assume that all pet owners whose pets get loose actually allow them to be loose, and that they don't care.
