One other benefit I noticed about having cats around. Mine wouldn't dig out moles but they'd sit and stare at a mole run when one was active. I'd pick up my .44Mag, give the cat a special treat and send it on it's way and blast the mole when I saw it move.
I despise moles. Yes it was absolutely a ridiculous amount of overkill. But a smokin' hole with visible mole parts always made me smile.
