Cats have both positive and negative connotations. You need to consider all of the details in the dream in order to obtain accurate interpretation. The cat can be a symbol of sexuality, femininity, prosperity and power. A cat is also an independent animal, and in your dream you may be associating yourself or someone else with these characteristics. Usually the dream is telling you about yourself and not others. Historically black cats have been symbols of evil and bad luck. If you are a cat lover and have one as a pet, the symbolism may not apply to your dream. Old, superstition-based dream interpretations say that a cat is a bad omen and that you can expect deceit from those that you trust.
