Me neither, I think that colour is just the society that we live in, it is a lot about looks, and if you go to a shelter that has a large amount of cats, something has to help your decision, and you can't always make one on their personality. We had a woman last week who wanted a black cat and wouldnt consider anything else, she ended up with 2 pure blacks we had!! I personally wouldn't opt for a black and white or a tortie, but then I have never truly picked a cat, they seem to find me, so it doesn't really matter what I would prefer!!
