The Animal in You is a 1995 non-fiction book by Roy Feinson, which posits a biological basis as to why people tend to exhibit personality traits similar to animal species.

The book hypothesizes that through the process of convergent evolution, people adopt a niche set of behaviors enabling them to cope with their particular social milieu in the same way as individual animal species adapt to their environments.

The book has been translated into ten different languages,[1] including Mandarin, Japanese, Czech, Hebrew and French, and has been featured on CNN,[citation needed] The Dr. Phil Show[2] and CBS The Talk[3][4][5][6] The Animal in You features a personality test of nine questions that collapses to one of 45 possible personality types.
