TNR has been done for years. DEFINITELY get involved in this, it's wonderful your town is considering this. The old thinking is just to kill them and that has gone on for years. Neutering and releasing them again actually works BETTER to control the population, but it's hard to convince public officials of that, not to mention the avid bird lovers who blame feral cats for every bird loss that occurs, despite the overwhelming evidence that it is us, humans, taking away the birds' habitat that is their biggest threat. [I could use that little gif of a soapbox here if I knew where to find it!] The TNR movement needs all the support it can get, and you belong in it!
