Some cays are definitely a bit higher on the brain utilization. My close relatives and I have seen cats ask for things, specifically do things they know piss you off in front of you, learn and play fetch, tattle on humans, attack door-to-door salesmen that were getting too pushy, and use a mirror to examine themselves. There's also stories of cats that got help from several miles away, woke up their humans when a fire started, chased bears off, comforted the dying specifically in their last week, and more than one that could rather reliably smell cancer.
And then there are those cats that are surprised when their whiskers are still there! XD
