I agree that you should get them good quality food and not the cheapest, but that doesn't mean "let them hunt and kill birds and mice." Not only does that lead to the decimation of bird populations (cats kill for sport) but your cat will have more health problems as they are much more likely to be exposed to worms, fleas, parasites, and fights. The life expectancy of an outdoor cat is significantly lower than that of an indoor cat.
And you are encouraged to take your cats on walks. My friend runs a line across his backyard and attaches the cat's harness to it. She gets to run around and the bell makes birds very aware of her presence. Telling people to keep them inside doesn't mean you don't play with them (I explicitly said the opposite). I should refine that you shouldn't let them roam outside. On a leash is fine.
People don't realize this, but you can in fact train cats. My cat does tricks.
