Humans can't purr and cats can't laugh

I was watching Randy Feltface with my cat sitting on my lap (not pictured, you degenerates will never see my lap), and I started just belly laughing at the bookshelf on gumtree skit, and I'm drunk enough to start wondering if my cat enjoys the sensation of my laughter as much as I enjoy the sensation of her purrs. A human is a ball of anxiety that can't purr to soothe itself and a cat is an utterly ridiculous creature that can never laugh at its own silliness. We'd be entirely screwed without each other.
