The Simpsons comes to mind. There's usually a plot, but it's not too complicated and each episode is self contained for the most part. Seinfeld is similar with possibly less plot (it is a show about nothing after all).
You forgot "pet my cat" and "feed my cat" and "cuddle with my cat" and "tell my cat that they already have food and won't be getting any more" and "feed my cat again".
