2a ANIMAL INTELLIGENCE 
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 nowise changed the 
opinions I expressed 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 modi- 
fications in some directions, hold for both. 
This apples 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, differences 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 toa 
slight degree, as compared with the intelligence she 
possesses. 
The cat is far in advance of the dog in power to 
execute highly complex co-ordinated movements. 
In both the dog and cat the play instinct is early 
and highly developed, but in the manifestation of this, 
the peculiar qualities of each are well exhibited.
