Cats domesticate us. They know a good deal when they see it. I take care of three cats that live at my shop. They came to me for food that I provided. They are useless with the exception I have not had one mouse in the shop in years. They like me, I think? They rub me with affection when I feed them. After they do not give a damn.
Forgot to add, like those worthless cats. I pet them in my lap and know the are using me.
