230 ANIMAL INTELLIGENCE 
will-power and intelligence, that this kitten bafiled 
human efforts in this case to go counter to its nature. 
I have been accustomed to encourage even young 
puppies, as soon as they are able to leave their nest, 
to form habits of cleanliness, but I have no notes on 
this subject at all so complete as in the case of this 
kitten, though some will be found in my first paper on 
the dog. 
But I now leave the reader with the diary before 
him to draw his own conclusions. 
The cat can be taught much, but her education must 
be conducted somewhat differently from the dog’s, 
because her nature is not in all respects like his. 
The dog, especially the pure-bred dog, is docility it- 
self. The dog may be forced to obey, the cat cannot. 
The dog usually delights to obey, or at all events to 
meet the approval of his master, and he only fails to 
make this evident when carried away by the force of 
his instincts. The cat may be coaxed or bribed into 
docility, but the latter is not a prominent feature in 
her character. 
It is a mistake, however, to suppose that the cat 
cannot be taught, and taught much, and I think the 
diary of the kitten, to go no further, shows this clearly. 
Certain it is, however, that one will learn more of 
the cat’s intelligence by quiet observation, than by any 
attempt to form her nature by education, after the 
manner so successful with the dog. 
The tendency of the kitten to arouse in the evening, 
and display an activity greater than during a large part 
of the day, is, to my mind, an early exhibition of a 
fundamental trait in the psychic life of the Felidae. 
They are essentially nocturnal animals, and to witness 
how early this was shown was interesting. 
I have noticed nothing like this in puppies, though 
it must be remembered that the cat is more like her
