Not at all. These efforts can be successful, especially when people pull together and don't allow for laxity until the project is finished. One of the city shelters we go to offering low-cost/high-volume spay neuter has done a phenomenal job over the last couple of years of getting the word out, keeping regular clinics (2/month), etc., and their annual cat intake has dropped by 300 since we started going up there. They're the exception rather than the rule, but even on a citywide scale it's possible to make a dent with relatively modest resources.
The trick in these neighborhood situations isn't just to get the cats who are there done, but to get it done before surrounding folks figure out that it's a place where they can dump their own unwanted cats. This appears to be more of a problem on farms -- many of the dairy folk who bring us cats swear that people keep dumping cats there, and I actually believe some of them -- but it can happen in cities, as well. Cat ladies attract cats even when they're not looking for them.
So keep up the good work. Hope feathers aren't too ruffled with the neighbs.
