Just Google for this complete string (include the quotation marks):

feral cats "Licensing and laws do nothing" "learned to evade all trapping methods" "SSS and TDSS Cat Management Programs"

I have posted that valuable (and lengthy) information on hundreds, if not thousands, of sites that bring-up the issue of free-roaming community-vermin cats.

Therein you'll find every effective method that you can employ to finally and permanently solve this invasive-species vermin cat problem completely in under 2 seasons of anyone’s time — no matter what laws govern your lives, no matter where you live, no matter how many cats infest your lands. And at costs affordable to any individual, any community, any nation. It worked 100% where I live -- and it only cost me 1/3rd-cent PER CAT for hundreds of disease-infested vermin cats infesting my lands. Total cost less than the price of two starbux coffees.
