Can Bombay cats have white and black on their fur?

Bombay cats are known for their solid black fur. They don't have any white or other colors in their coat.

The breed standard specifically states that Bombay cats should have a deep, glossy black coat with no white markings.

So, if you see a cat with both black and white fur, it's not a purebred Bombay. It's likely a mixed breed cat with Bombay features, or a Bombay that has been bred with other breeds.
