So why don't black cats get adopted? First, a lot of people simply don't like black cats. They think they're mean. That's according to UC Berkeley researchers, who had people complete a questionnaire about cats. The result? Orange cats are considered friendly...White cats are believed to be quiet and shy...But most people had a negative opinion about black cats. As a result, orange or Siamese kittens are usually adopted within their first day at a shelter. But black cats can be there for months. Then there's the perception that black cats are unlucky. It started in the Middle Ages, when black cats were associated with the Black Plague - and all but killed off - even though they had nothing to do with spreading disease. Then, in the 16-hundreds, black cats became associated with witchcraft. Another reason black cats don't get adopted is totally modern - and it's because black cats don't photograph well. So it's harder to see their features in pictures on adoption websites. And even if they do get adopted, some people are returning them! According to the SPCA, cat owners are reportedly surrendering their black cats because they don't look good in selfies. But if a black cat doesn't look good in your selfie, blame the photographer, not the model. And the truth is - black cats aren't unlucky - and they're not mean. In fact, a lot of black cats are Bombay breeds, which were bred to look like miniature panthers - and they're known to be sociable and easy going. If that doesn't sell you - consider this: Black fur won't show on your little black dress.
