My post: There seems to be a problem with someone's math. Here it is, they take a cat from a neighborhood to be neutered, then they release it. Net loss? Zero!
Oh, wait a minute... Logically, we have to surmise more cats will be attracted to all of the feeders, plus more unwanted cats will be dumped there as it becomes known they are taking care of them. End result? KaChing! KaChing! More cats!
