Actually, when we adopted Shiloh they were thrilled. Seems it's very very hard to place black cats and kittens. They had a 7 month old black female there that we didn't see till we'd gotten Shiloh. She was a doll and if we'd have had more room we'd have taken her too. Room is our only issue. So three it is for now.
Some of the best cats I've even owned have been black.
