The subject is pretty self explanitory, but I would like to bring to the table information about typing animals. Because animals live and cope in the same environment as us, they most likely have similar cognitive functions. I personally have two cats and observe interesting correlations between their outward behavior, their relation to me, their abilities, and the people they remeind me of in terms of the feeling i get around them. Cat x is a male cat and seems to be very good at figuring out mechanical problems, such as opening doors and such, me is also introverted and avoid people. When staring at him, he will try to ease his tension by making an inqiry type of sound implying (whats up? why are you staring at me?) and he will continue to observe me staring in an uncomfortable way. He is also graceful and remembers his environment visually. When he steps over an object with his front paw, he will step over it with his hind paw as well without having to look. So he most likely has a very good extraverted spatial sense. I am assuming he is ISTj. My other cat, a female, is very bad at figuring out mechanics, is clumsy, runs into objects. she has very good emotional abilities and can manipulate alot better than cat x, using sound. It is as if she sings. she also loves people, is very energetic and is not gentle. She is much better at controlling her emotions and will continue to purr, even if being scolded. She seems to be ENFJ. I also feel as if her primary function affects my suggestive function. We also make intimate eye contact which is different from th eother cat. It definitly reminds me of ENFJ's. Now that I am developing feelings I can better correlate the feelings I get about my relations with others. Before you judge my claims.... remember I am not using pure logic, to observe and define my observations. There are relational ethics and intuition involved as well. So if you do not believe my statements, it is because you ar eunable to replicate my subjective obervations, due to a lacking of specific functions that I used, or subject animals. But you can also look at it this way... evolution rarely skips a step, and if all animals are less evolved (in terms of intelligence) versions of humans, then they must have begun to form personality differences in order to create a desire to socialize for the benefit fo the entire group.
