A new study found house cats aren't much more docile than lions. If they were bigger and you tried to keep them as pets, they'd probably kill you.

Cat experts rated the felines' behaviors based on the big five human personality traits:

  1. Openness to Experience
  2. Conscientiousness
  3. Extraversion/Introversion
  4. Agreeableness
  5. Neuroticism

According to the research, domestic house cats and African lions have similar personality structures. Both have strong characteristics related to dominance, impulsiveness and neuroticism.

If you have ever thought your cat was anxious, insecure, tense, suspicious, or aggressive toward you, you aren't making it up. If they were bigger, your cats would probably consider killing you.

But the news isn't all bad: just like lions, house cats are also playful, excitable and impulsively hilarious.
