THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 189 
35th day.—Growing well. Weighs 1}]bs. Is given 
milk, then placed in pan and uses it. 
To-day when called “Puss! puss!” as it lies behind 
the barricade, it comes out. 
Now manifests pleasure in being stroked. 
Its vision is now so keen it can rapidly follow 
movements of the fingers, etc. 
It scrambles into the book-shelf by a new way and at 
a much greater height. 
Is seen to catch at its own tail for the first time. 
Two Skye terrier puppies are brought near the kitten. 
It makes a great fuss, showing all the signs of anger, 
etc. 
Some cooked jfish (of which cats are notoriously fond) 
was placed before the kitten. It licked this but did not 
eat any, though there seemed to be a certain amount of 
surprise and excitement. 
36th day.—tThe day is dull, and the kitten, lies in its 
box a great deal in the forenoon, though later it rouses 
itself and plays with its mother. 
I try for some reason to intercept the kitten when it 
makes a long run to escape. 
To-day, for the first time, it crosses the threshold of the 
room door, but was scared back. ! 
For the first time, too, it sinks its claws into an upright 
object, as an old cat often does. 
Some raw meat is placed before its nose. It snzffs at 
this, but makes no attempt to eat it. 
It begins to understand better the meaning of the 
call “ Puss! puss!” 
Its manner of play now much more active and com- 
plicated. 
Is noticed stalking on two occasions to-day—once 
towards the mother’s moving tail. 
37th day—This morning early the kitten enters the 
pan, of its own accord, and functions.
