The Animal in You Quiz - Personality Test will tell you which animal best suits your personality. Unfortunately the site is down. Given that it is at the top of Google Trends it probably got more traffic than the site could handle. Once the site comes back up you can get to the test here:animalinyou.com/survey.asp.
Animology is when we wonder what we would be if were reincarnated as animals. Personalities and moods are compared and contrasted in this quiz as you are fitted into your animology animal. I hope the site comes back up soon. I wonder what animal will fit my mood.
