For nesting season, I agree. Otherwise, it is rather pointless. Funny thing is, I had a neighbor just like you. One day a feral cat strolled in, ignored his huge dog and made himself at home. He's still there, coming and going as he pleases.
"One day a feral cat strolled in"
One day a feral cat strolled into my yard. Zap, he vanished. That happens every few days now.
