A neighbor of mine started feed a couple stray cats. The population has exploded. Unlike OP's area, there's not really any support for TNR programs in my area. It's horrible for the cats, the neighbor that fed them moved. So, the cats are malnourished, infested with fleas and mites, get attacked by dogs in the backyards. It's horrible for the homeowners too since these cats are marking their territory which is stinking up the sides of the homes, outdoor furniture and they are tearing up gardens. When I first moved here, there were tons of hummingbirds. Haven't seen one in awhile and I miss them.
