I believe it's very impawtant to spend time with your hoomins, and be affectionate. They need attention every day from their kittehs, or else they can get cranky. Or feel unluffed. We don't want that!
Me, I am a head-bonker. And I enjoy rubbing noses with my Mom. We lay on the pillow together, where I purr and pet her on a regular basis. Then I can sleep, knowing I've contributed to my hoomin's health and happiness.
