Cats respond better to women than to men, 

probably due to the fact that women's voices have a higher pitch.

The house cat can hold it's tail up while walking.
It's the only cat species which does that!
The wild cat's tail is kept horizontally or between their legs.
One of the meanings of Cat's tail up is: I am not afraid!
The cat in the picture, tells the dog, with the universal animal language: I am not afraid of you !
