I think it would be the most humane solution. Before anyone starts fireing at me know that I am a HUGE animal lover, that's WHY I say that. If you have lived in the country and seen the dogs and cats that run wild, slowly starving becomming diseased, and breeding rampantly then you know what I mean. Anytime you have an imbalance in species, like what is going on with the cats there, it WILL affect the wildlife in the area. So it is very possible that they cats could wipe out some species of birds and small rodents as well.
