When Do Bengal Cats Stop Growing? How Big Do They Get?

Bengal cats are of wild ancestry, and this can leave many owners, and prospective owners in particular, with a lot of questions to ask about their pets. One of the most common questions new Bengal cat owners have concerns when their Bengal cat will stop growing.  

Most Bengal cats stop growing by the age of two, but some have been known to reach full size as early as 18 months or as late as three years. Their size depends on several factors, but an adult Bengal cat will weigh between 8-15 pounds and will be 16-20 inches long with a height of 10-16 inches.

While there is an average age when Bengal cats stop growing and reach full size, several factors play into your cat’s actual size and when they stop growing. Factors range from gender and lifestyle to neutering and genetics. We’ll dive into these factors below.

Are Bengal Cats Bigger Than Normal Cats?

Bengal cats can be bigger than normal cats. Bengal cats are an average large-sized cat breed, but because Bengals exist as a result of the crossbreeding of the domestic cat and the Asian Leopard Cat, they may get to be bigger in size than your average domestic shorthair.

But due to their active lifestyle and lean frame, they will probably weigh less than a normal cat. There are six stages of growth for Bengal cats. Here’s a chart to compare the size of the Bengal cat with your average tabby cat:

8-12 pounds10-14 pounds
14-16 inches tall10-16 inches tall
16-20 inches long13-16 inches long

When Are Bengal Cats Fully Grown?

Bengal cats are fully grown between ages one and a half and three years old. It’s important to keep in mind, however, that there are age stages to all cats and their size may shift as they mature through these different stages. However, between 1.5 and 3 years old is a good estimate for maturity.

Although they should reach their full size in terms of height and length by age three, their weight may fluctuate as they reach these different age stages.

The chart below will give you an idea of your Bengal cat’s weight by age stage, but “fully grown” may be relative as weight can fluctuate over time. Fluctuations can be due to changes in diet or decreased activity and decreased metabolism as cats get older. Senior and Geriatric Bengal cats may even become smaller compared to their Prime and Mature stages.

Kitten (0-6 months)0-8 pounds
Junior (7 months-2 years)6-12 pounds
Prime (2-6 years)8-12 pounds
Mature (7-10 years)10-14 pounds
Senior (11-14 years)8-12 pounds
Geriatric (15+ years)6-11 pounds

Do Bengals Grow Faster Than Other Cats?

Bengal cats usually grow a little slower or at the same rate as other cats. Most cats are considered fully grown between six months and one year old, whereas Bengal cats can take up to three years to become fully grown.

Although it depends upon the breed of cat, it’s unusual for a cat to grow past the age of two, so in that respect Bengal cats are quite unique. Bengal cats hit six growth stages as they’re maturing.

If you want to get a good idea of when your cat will stop growing and how big your Bengal will get, you may want to journal their weight, height, and length at each stage. Think of it like a parent marking their child’s height on the wall as they grow up.

Tabby cats grow at a faster rate early in life, then stop around age one, whereas Bengal cats have a slower, steadier growth rate that happens in six stages.

Here are two charts to show you the growth rate of Bengal cats compared to a typical tabby:

5 weeks old14 oz-1.8 pounds
8 weeks old1.4-2.5 pounds
14 weeks old3-5 pounds
5 months old5-8 pounds
1 year old10-14 pounds

How Big Do Bengal Cats Get?

An average-sized Bengal cat gets to be around 11 pounds, 12 inches high, and 18 inches long. Some will be bigger or smaller depending on various factors, such as genetics, diet and exercise, and gender.

However, there are some unusual aspects to how big Bengal cats get. For example, Bengal cats tend to have back legs that are longer than their front legs. If you notice this about your Bengal cat, it’s not a deformity! It comes from their Asian Leopard Cat ancestry.

Other interesting things to note as you’re tracking your Bengal cat’s size is that they generally have longer tails and bodies than regular domestic cats. This is also due to their wildcat roots.

What Factors Affect How Big Bengal Cats Get?

There are several factors that can affect how big Bengal cats get. One of the first ways to tell if you’ll have a larger or smaller Bengal cat is its gender. Other factors that affect how big a Bengal cat gets is diet and exercise, choice to neuter, genetics, and birth order.

How Diet And Exercise Affect How Big A Bengal Cat Gets

Since diet and exercise affect how big a Bengal cat will grow, it’s important that they have plenty of protein in their diet to reach optimum size and weight. Bengal cats are also a lot more active than some other breeds (this isn’t a lap cat breed!), so they need plenty of exercise. Regular exercise will keep your Bengal cat lean and its growth at a normal rate.

How Neutering Can Affect How Big A Male Bengal Cat Gets

Neutered male cats have lower testosterone levels than unneutered male cats.Male Bengal cats are generally larger than female Bengals, and an unneutered male cat will be even larger than if you have it fixed before it hits puberty.  

This difference causes unneutered male cats to have large heads and puffier cheeks. This can make an unneutered male Bengal cat appear larger and weigh more than one that is neutered. If you want to limit this in your Bengal cat, it’s best to neuter before the age of five months, since that’s when male cats reach sexual maturity.

However, it’s interesting to note that neutering your male Bengal cat may make it taller. Neutering your Bengal kitten will delay the closure of its bone growth plates, so they can become longer than if they aren’t fixed. This may also mean that your Bengal cat will stop growing later than if it wasn’t neutered.

How Genetics Affects How Big A Bengal Cat Gets

The breed of domestic cat your Bengal cat originates from can have a large impact on how big your Bengal cat will get. For example, let’s compare two of the types of domestic cats used in breeding Bengals: the Abyssinianand the British Shorthair. An Abyssinian will likely not grow to more than 10 pounds, whereas a British Shorthair can get as big as 18 pounds.

Check with the breeder or rescue to ensure your Bengal cat comes from healthy parentage. Genetic disorders or malnutrition in mom or dad could mean your kitten will not grow to be as big as if its parents were healthy when your cat was born. Cats that did not get proper nutrition from birth will end up being smaller in size than those who nursed from a mom with plenty of milk rich in nutrients.

How Birth Order Affects How Big A Bengal Cat Gets

Birth order can also affect how big a cat will get. Ever heard the expression, “runt of the litter?” Runts are the smallest in a litter of cats and birth order can be a good indicator of whether your Bengal kitten will end up being smaller (6-10 pounds) or larger (8-12 pounds). If your cat is farther down the line in a large litter, chances are it may not get as big as the first born.

Also keep in mind that the larger the litter is, the more kittens there are to share the milk supply. Have you ever seen a litter of cats fighting over milk? Or one kitten nursing longer than the others? Kittens who aren’t feeding as much or able to get as much milk may be smaller than those who nurse longer or more often.

Final Thoughts

Bengal cats typically stop growing by the age of two, but some will continue growing for another year. While there are many contributing factors, full-grown Bengal cats weigh between 10-15 pounds, and reach a height of 14-16 inches and a length of 13-20 inches.
