How Long Do Bombay Cats Grow? A Complete Guide to Their Growth and Development

The Bombay cat breed originated in the United States in the 1950s. They were created by breeding sable Burmese cats with black American Shorthairs, aiming to achieve a sleek and muscular black cat with copper or gold eyes. This breed was named after the city of Bombay (now Mumbai) in India, known for its black leopards.

Physical Characteristics

Bombay cats are medium-sized with a muscular build, giving them a sturdy and compact appearance. Their glossy black coat is short and close-lying, accentuating their sleek silhouette. One of their distinctive features is their expressive eyes, which are usually gold or copper in color. Their rounded head, medium-sized ears, and straight nose contribute to their overall balanced and elegant look.

Personality Traits

Bombay cats are known for their friendly and affectionate nature. They thrive on human companionship and enjoy being part of the family. These cats are often described as social butterflies, as they love interacting with their owners and even strangers. They are highly intelligent and active, always curious about their surroundings. Despite their playful nature, they also appreciate quiet moments and can be quite cuddly and affectionate.

Growth Stages of a Bombay Cat

Neonatal Stage

The neonatal stage is the first two weeks of a Bombay cat’s life. During this stage, they are completely dependent on their mother for nourishment and warmth. Their eyes and ears are closed, and they spend most of their time sleeping and nursing.

Kitten Stage

Around the age of two weeks, Bombay kittens begin to open their eyes, revealing the stunning color that will captivate their owners. They start exploring their surroundings, stumbling and wobbling as they learn to walk and play. This is an important stage for socialization, as they interact with their littermates and learn important feline behaviors.

Adolescent Stage

The adolescent stage occurs between four to eight months of age. This is a period of rapid growth and development, where Bombay cats experience significant physical and behavioral changes. They become more coordinated and agile, and their energy levels soar. It’s during this stage that they start to resemble adult cats, both in size and appearance.

Adult Stage

By the time Bombay cats reach their first year, they have typically reached their full size and weight. Adult Bombay cats are muscular and lean, with a graceful and athletic physique. Their playful nature may continue into adulthood, but they also become more calm and composed, settling into their role as a beloved family companion.

Factors Affecting the Growth of Bombay Cats


Genetics play a significant role in determining the growth and size of Bombay cats. Breeding practices and the selection of parent cats with desirable traits can influence the overall growth potential of the breed. It’s important to obtain Bombay cats from reputable breeders who prioritize health and genetic diversity.

Diet and Nutrition

Feeding your Bombay cat a balanced and nutritious diet is essential for their growth and development. Kittens require a diet rich in protein, essential fatty acids, and other vital nutrients to support their rapid growth. As they transition into adulthood, maintaining a healthy diet is crucial to prevent obesity and ensure their overall well-being.

Environmental Factors

The environment in which a Bombay cat grows can also impact their growth. Providing a safe and stimulating environment that encourages physical activity and mental enrichment can contribute to their overall development. Access to interactive toys, scratching posts, and climbing structures can help promote healthy growth and prevent sedentary behavior.

Understanding the Growth Rate of Bombay Cats

Timeline of Growth Milestones

While the exact timeline may vary from cat to cat, it’s helpful to have a general understanding of the growth milestones of Bombay cats. By around six months of age, they will have achieved most of their physical growth. However, their muscle tone and coordination will continue to improve into adulthood.

Average Size and Weight for Each Stage

On average, Bombay kittens weigh between three to four pounds at three months of age. By six months, they can reach around six to eight pounds. Once they reach adulthood, Bombay cats typically weigh between eight to fifteen pounds, depending on their gender and individual genetics.

Monitoring Your Bombay Cat’s Growth

Weighing and Measuring Techniques

Regularly weighing and measuring your Bombay cat can help you track their growth progress. Use a pet scale or weigh yourself first and then hold your cat while standing on the scale to calculate their weight. Measuring their length and height can also provide valuable insights into their growth.

Signs of Healthy Growth

In addition to monitoring their weight and size, there are other signs that indicate healthy growth in Bombay cats. A shiny and lustrous coat, bright and alert eyes, and a playful and energetic demeanor are all positive indicators of proper growth and development. Regular veterinary check-ups can also help ensure their overall health.

Promoting Healthy Growth and Development

Proper Nutrition and Feeding Guidelines

Feeding your Bombay cat a balanced and appropriate diet is crucial for their growth and overall well-being. Consult with your veterinarian to determine the best type of food and portion sizes for your cat’s age and activity level. Avoid overfeeding and provide fresh water at all times.

Physical and Mental Stimulation

Engaging your Bombay cat in regular play sessions and providing environmental enrichment can promote healthy growth and prevent boredom. Interactive toys, puzzle feeders, and designated scratching areas can keep them physically and mentally stimulated, ensuring their overall growth and happiness.

Veterinary Care and Check-ups

Regular veterinary care is essential for monitoring your Bombay cat’s growth and addressing any potential health issues. Schedule routine check-ups, vaccinations, and dental cleanings as recommended by your veterinarian. They can provide valuable guidance and ensure your cat’s growth is on track.

Common Growth and Development Issues

Fading Kitten Syndrome

Fading Kitten Syndrome is a term used to describe a condition where kittens fail to thrive and grow as expected. It can be caused by various factors, including underlying health issues, inadequate nutrition, or poor maternal care. Prompt veterinary attention is crucial if you notice any signs of weak growth or decline in health.

Kitten Growth Spurts

Just like human children, Bombay kittens can experience growth spurts during their development. These periods are characterized by rapid growth and increased appetite. It’s important to provide them with appropriate nutrition and monitor their weight during these times to ensure they are getting the nutrients they need.

Delayed Growth or Stunted Development

In some cases, Bombay cats may experience delayed growth or stunted development due to underlying health conditions or improper care. If you notice that your Bombay cat’s growth is not progressing as expected or they are significantly smaller than average, consult with your veterinarian to rule out any underlying issues.


Understanding the growth and development of Bombay cats is essential for providing them with the care they need to thrive. From their neonatal stage to adulthood, these captivating felines undergo significant physical and behavioral changes. By monitoring their growth, providing proper nutrition, and ensuring a stimulating environment, you can support their healthy development. Remember to consult with your veterinarian for personalized guidance and enjoy the journey of watching your Bombay cat grow into a magnificent companion.
