It's generally not advisable to purchase a Bombay cat priced at $800, as it's highly likely to be either a mixed-breed cat or a "sickly" cat (often called a 'week cat'). Typically, even a Bombay cat with average characteristics will cost around $3,000. Any price significantly lower than the market average is cause for concern.

An $800 Bombay cat is unreliable and most probably a mixed breed or a 'sickly' cat. Generally, a Bombay cat with average characteristics costs around $3,000, a purebred Bombay is usually priced at $5,000 or above. A purebred Bombay cat with a pedigree certificate will be even more expensive, generally starting at $10,000 or more. The market price of a Bombay cat varies depending on factors such as its quality, bloodline, and market conditions. Of course, prices will also vary in different economic regions. It is not recommended that you buy any Bombay cat priced too far below the market value to avoid being scammed.
The Bombay cat was created in 1958 by an American breeder by crossbreeding Burmese cats with American black shorthair cats. It is truly a modern breed. Due to its appearance, which resembles a leopard, it was named after the Indian city of Bombay. The price of a Bombay cat can range from several thousand to over ten thousand dollars, depending on its quality, lineage, and breed. Bombay cats are actually quite easy to care for as a pet.
