This question can be heard quite often from future owners. Indeed, the Bombay breed is positioned as a black cat breed only. But is it really so? Let's look into it.
Before giving an unambiguous answer to this question, it is worth delving into the history of the creation of the Bombay breed. The breed was created by crossing the Burmese and American Shorthair breeds. The Bombay inherited its texture of hair with a characteristic lack of undercoat, skeleton and powerful muscles from Burmese cats, and from American Shorthair - black hair color. To this day, the number of Bombay cats in the world is so small that many felinological associations allow interbreeding of Bombay and Burmese cats, as they belong to the same breed group.
Would a kitten born of a pair of Bombay and burmese be considered a Bombay? Yes, it will.
Despite the fact that it might be a different color than black? Yes, regardless. Such a kitten would be referred to as a "Bombay of a non-standard color".
Can a nonstandard colored kitten be born from a pair of two Bombays? Yes, it can. Many Bombays in recessive have non-black colors that when found in one of the kittens results in a non-black color. As a rule, the most common are sable and blue colors.
Color, as we know, does not affect the character, so the kitten will have the very features for which we so love Bombay: he will be curious, playful and sociable. As many breeders notice, such kittens are very charismatic and are not inferior in appearance to their black-colored brothers and sisters.
