The ideal Bombay is medium-sized with substantial bone structure and good muscular development, a cat that feels surprisingly heavy for its size. The head is pleasingly rounded with no sharp angles, and the face is full with considerable breadth between the eyes. The muzzle is broad and moderately rounded.
American Burmese and Bombays alike are commonly bred in two types:
The coat, one of the breed's nicest features, is fine and close-lying with a patent leather sheen. The short satiny fur feels like warm velvet to the touch. Only one color and pattern is accepted solid black.
If you have a true bombay and follow the rules for allowed out crossing, sable American Burmese or black American shorthair with at least 3 generations of black, there will be no lilac, blue or chocolate kittens!
Although most breeding programs produce a certain number of sable-colored cats. To maintain the desired head, body and coat type, breeders cross their Bombays with sable American Burmese. This creates certain problems. The gene governing the sable color is recessive, and the gene for black is dominant. If a Bombay has one copy of the black gene and one of the sable gene, as many Bombays do, the cat will be black but will carry sable and can pass it along to the offspring. Any cat that inherits a copy of the sable gene from both parents will be sable.
Kittens after one Burmese parent and one Bombay may be registered and shown as Burmese by some organizations. This is how they do it in French LOOF.
In CFA it still allowed to use both sable American Burmese and black American shorthair to outcross whilst in TICA it is only allowed to use the sable American Burmese.
Late bloomers and early breeders:
Bombay kittens look very ordinary. The magnificence of the cat-to-be does not begin to emerge until kittens are about four months old, when they develop sleek, shiny coats and penetrating eyes.
Bombays mature very slowly. The earliest sale should be 12 to 14 weeks, and even then their quality is still difficult to assess. Show quality may not begin to be evident until six to seven months. A rough coat may transform itself into a short, sleek and shiny coat covering a well-muscled body. Some of them has not finished maturing until the age of 18 months , and they continue to mature and improve with age.
While Bombays are slow in developing external breed characteristics, they are precocious when it comes to breeding: Some are sexually active as early as five months, though seven to eight months is the average. The Bombayís relatively early sexual development in a result of itís hybridization.
