Field Notes
Bombay Lifespan, Size, and Care
The Bombay was developed in the United States in the 1950s by breeder Nikki Horner, who crossed sable Burmese cats with black American Shorthairs to create a cat with the look of a small black panther. The breed was later recognized by major cat associations and remains relatively uncommon compared with many other pedigree cats.
Temperament-wise, Bombays are usually social, curious, and deeply attached to their people. Many are described as "Velcro cats" because they like to follow family members from room to room, join daily activities, and seek out laps, warmth, and attention.
For care, Bombays do best on a measured, high-quality diet because they can gain weight easily if overfed. Routine veterinary visits, dental care, nail trims, litter box hygiene, and environmental enrichment are all important, and many Bombays also do better when they are not left alone for long stretches.
Exercise needs are moderate to fairly high for an indoor cat, especially when Bombays are young. Daily interactive play with wand toys, balls, climbing trees, food puzzles, and short training sessions helps prevent boredom, supports a healthy weight, and gives this intelligent breed an outlet for its athleticism.

Bombay Feeding Guide
Use this Bombay feeding guide as a starting point for common life stages, then adjust for body condition, activity, and veterinary advice.
Formative years
Young
Feed a complete kitten formula in several small measured meals each day, with the exact amount adjusted to growth rate and body condition. Kittens should stay on a growth diet until your veterinarian confirms they are ready for adult food.
Peak years
Adult
Feed a complete adult cat food in measured portions and monitor body condition closely, because indoor cats often need fewer calories than owners expect. Wet food, fresh water, and routine portion checks help reduce weight gain and support urinary health.
Mature years
Senior
Older cats often need closer monitoring of weight, appetite, hydration, and dental comfort even before a full diet change is needed. Ask your veterinarian about senior diets if kidney disease, thyroid disease, muscle loss, or digestive changes start to affect intake.

On the Bombay
That depends on the pet's actual age. Use the calculator above to estimate a Bombay's age in human years using the method shown on this page.
A healthy Bombay often lives around 12 to 16 years, and some may live longer with excellent care. Lifespan is influenced by genetics, body weight, dental health, preventive veterinary care, and early detection of medical problems.
A full grown Bombay usually weighs 3-5 kg, though sex, lineage, and body condition can move an individual above or below the average range.
Most Bombays are close to full size around 12-18 months, although growth rate and final build vary from one pet to another.
Use the feeding guide above as a starting point, then adjust for age, body condition, activity, and your veterinarian's recommendations.
Bombay cats are generally affectionate, social, and strongly people-focused. They usually do best with owners who want an interactive cat and can provide regular attention, play, and companionship.
Bombay cats can do well with children, other cats, and even cat-friendly dogs when introductions are handled properly. Their outgoing nature often helps them adapt, but they still need respectful handling and a safe place to retreat.
Bombays need regular interactive play and mental enrichment to stay healthy and prevent boredom. Cat trees, scratching posts, puzzle feeders, and short sessions of fetch or wand play are excellent ways to meet their activity needs.
