whose nature, as I have pointed out,’ seemed after a time to develop with 
great rapidity under the impulse of experience, was a rival in this respect 
with the cat; but that case is exceptional I must believe. 
As regards reasoning, I have in no wise changed the opinions I ex- 
pressed in my first paper on the dog, and I would apply them with 
almost if not quite equal force to the cat. 
Some General Conclusions. 
The conclusions that may be drawn from the diaries of the dog and 
the cat respectively, with certain modifications in some directions, hold 
for both. 
This applies especially to the larger proportion of what is most 
fundamental—to what is instinctive and is bound up with the vegetative 
life of the creature. 
Nevertheless, even in some of these fundamentals of psychic life there 
are differences, e.g., in the mode of waiting for and securing prey, differ- 
ences which appear long before development is complete. 
Upon the whole the cat develops more rapidly than the dog. 
The greatest difference between the cat and the dog is in their 
relations to man and to their own species. 
The dog is essentially a social and a gregarious animal; the cat an 
independent and solitary creature, traits which are early shown. 
The dog is docile in the highest degree ; the cat to a slight degree, 
as compared with the intelligence she possesses. 
The cat is far in advance of the dog in power to execute highly com- 
plex co-ordinated movements. 
In both the dog and the cat the play instinct is early and highly de- 
veloped, but in the manifestation of this the peculiar qualities of each 
are well exhibited. 
In will-power and ability to maintain an independent existence the 
cat is superior to the dog. 
In the higher grades of intelligence the wisest dogs are much in 
advance of the most knowing cats, which is foreshadowed if not actually 
exemplified in the early months of existence. 
The nature of the dog as compared with the cat tends to beget 
prejudices in his favour with the mass of persons in any comparisons as 
to intelligence, desirable qualities, etc., so that there can be little doubt 
that in general the dog is overestimated and the cat underestimated by 
the great majority of persons; at the same time the nature of the dog is 
much nearer that of man’s than is the cat's. 
The kitten may amuse, but even a puppy dog touches chords of 
sympathy in the heart of man that the cat can never reach.
