I have some to add

Caltitude: Exactly how high a cat's rear end will raise when pet or in order to meet a potentially petting hand. The measurement of elevator butt. Example: Howard's butt can reach a caltitude of three to five inches when his meowme pets him.

Head Scrub: An very over-enthusiastic head bump (n). When a cat rubs its head in a circular motion into a person or an object (v.) This act is typically performed when less drastic demands for attention (mews, gentle head bumps) are not met to the cat's satisfaction and can almost be painful to the receiver.
