The best way to reduce feral cat populations - which will reduce the number of kitties that are brought in by well-meaning animal lovers - is "trap-neuter-release"...

The result of unsterilized, domestic cats who were abandoned or lost, feral cats are born and grow up without human contact. They distrust humans and revert to the ways of their wild ancestors. Attempting to tame them is difficult, time consuming, and only occasionally successful.
The number one killer of domestic and feral cats in the United States is death in shelters due to overpopulation. For many years, the methods of choice to deal with feral cats have been to ignore or attempt to eradicate them. Neither method has solved the problem of their overpopulation.

Eartipping provides instant identification for managed ferals. Trap, neuter and return is the only method of population control for feral cats that actually reduce their numbers. The evidence from established TNR programs in the U.S., in Europe and around the world is proving that TNR is decreasing the populations of feral cats where eradication attempts have failed.
