Cats aren’t hard-wired to be couch potatoes. They are meant to hunt and pull the guts out of the helpless creatures that keep them alive. It’s not pretty but it’s nature’s way. You can import a dozen lab mice to turn loose in your living room (not a good idea, really) or you can provide all of your cat’s food from food-dispensing toys like the Twist ‘n Treat that Gaston is scavenging from. He expends energy and stays busy doing work that is similar to his innate survival skills. And he’s taken off a bit of that holiday weight gain. He has another food toy that he pushes around to get dry food. He never eats from a bowl. It wouldn’t be natural.
