"Scientists at first were skeptical that a kitten-type being could exist in the rare Martian atmosphere. As a test, two Earth kittens were put in a chamber that simulated the Martian air. The diary of this experiment is fascinating:
6:00 A.M.: Kittens appear to sleep.
7:02 A.M.: Kitten wakes, darts from one end of cage to another for no apparent reason.
7:14 A.M.: Kitten runs up wall of cage, leaps onto other kitten for no apparent reason.
7:22 A.M.: Kitten lies on back and punches other kitten for no apparent reason.
7:30 A.M.: Kitten leaps, stops, darts left, abruptly stops, climbs wall, clings for two seconds, falls on head, darts right for no apparent reason.
7:51 A.M.: Kitten parses first sentence of daily newspaper that is at bottom of chamber.
With the exception of the parsing, all behavior is typical of Earth kitten behavior. The parsing activity, which was done with a small ball-point pen, was an anomaly."
