"Cat behavior includes body language, elimination habits, aggression, play, communication, hunting, grooming, urine marking, and face rubbing. ... Some cats ask for food dozens of times a day, including at night, with rubbing, pacing, and meowing, or sometimes loud purring (Wikipedia, Oct 2019)
In psychology Thorndike studied cat behavior in details. You can see it on youtube. I showed it to my students. Wikipedia writes: "The essential idea is that behavior can be modified by its consequences, as Thorndike found in his famous experiments with hungry cats in puzzle boxes. The cat was placed in a box that could be opened if the cat pressed a lever or pulled a loop."
Actually mice and cats are very clever, indeed.
Researchers from UK video-filmed cats to study if the cats were more attached to humans or to other cats. The result showed that the cats were more attached to humans (and so is my cat while I am the one who feeds it. It also likes to be close to me in the late evening for a while before it goes into another room to sleep).
