Cats as a rule suggest psychic ability, sexuality, secrets, sensitivity, affection, independence, intuition, emotion, jealousy, anger, stealth, or vindictiveness. They also symbolize a hidden side of ones own nature.

Black is symbolic of secrets, hidden things, and the unknown or the unseen.

Do these guys remind you of anyone you know? Some people believe that cats have the ability to travel between different planes of existence. That they are oracles of a sort and can fortell the future.
It could be that you are trying to decide between to people, and your subconscious(the cat) already knows which one is the best for you....as a lover or a friend.

Hope this helps, good luck!
