228 ANIMAL INTELLIGENCE 
interesting record bearing on this subject. In fact, 
from this point of view, the cat, during the first three 
months of its life, is decidedly in advance of the dog. 
In the mature cat, instinct in securing prey plays so 
prominent a part, that we are apt to overlook a great 
deal in the mental experience of the cat. Her psychic 
life is withdrawn from us to a greater extent than that 
of most of our domestic animals. I do not know of a 
single good history of the complete development of the 
cat from birth to maturity, so that I regret the more 
the loss of my kitten before she had reached the age of 
at least one year. 
The diary also shows that the cat has a good memory, 
though whether equal to, or better than, that of the 
dog, I am not prepared to say; the evidence is in- 
sufficient for the purpose. 
On the question of will-power there is, however, 
ample evidence for making comparisons. 
If the quivering movements of the ears were im- 
perfect voluntary movements, these may be considered 
about the first manifestation of will in the kitten, and 
there is nothing to correspond to this in the dog at so 
early a state. 
While attempts to get from the original nest or 
home took place at an early period in both the dog 
and the cat, they were more persistent in the latter. 
I have given, in considerable detail, the history of the 
kitten’s attempts to get into my book-shelves, etc., and 
I must repeat that this furnishes to me the most im- 
pressive evidence of the existence of a strong will- 
power, intelligently expressed, that has ever come 
under my observation in so young an animal of any 
kind. While I think that the kitten, whose history I 
have recorded, was above the average in strength of 
character, if 1 may so express it, yet, in making all 
allowance for this, there is still a very large margin in
