I don't think there are many creatures on the Earth that can relax the way a cat can.

They sleep the way I imagine I would sleep, if I didn't have things to worry about. Like keeping a roof over our heads and kibbles in the dishes, or have I impressed this person because maybe they can hook me up with a job, or would the guy I like like me back if I was skinny, or can I get my car to run all right until I have a job and can afford to fix it up properly, or I need to take Simon to the vet but have no idea how I'll pay for it.

Ah, to be a cat with so light a conscience that "unconsciousness" could just envelop me, like the warmest, softest, blanket.
