We adopted a handsome feral stray tomcat about a year ago (now neutered). I wish he would stick to squirrels, rabbits, gophers and leave the birds and lizards alone—the one thing I don’t like about him is the toll of ~50 birds a year, at least. But I respect the nature of an animal designed to kill and eat prey.
He’ll stand up on hind legs to get at it, which is hilarious. Gotta think it’s far more healthy than cat treats with nasty fillers and preservatives.
