When Will My Ferret Stop Growing?4 min read

Ferrets are a popular pet in America, and for a good reason. Ferrets are cute, cuddly, intelligent creatures that make excellent pets! Your ferret’s growth will depend on gender and breed.

Read on to find out more about at what age ferrets stop to grow.

First Off: No, ferrets do not grow forever. Ferrets stop growing once they reach adulthood and their full size is reached.

The size difference between males and females cannot be seen until adulthood, but usually, females are around two-thirds the height of their male counterparts at adult heights.

Male ferrets are generally larger than female ferrets, but both genders can be between 4 and 7 pounds when fully grown. Ferrets typically reach their full size at four months old, but some breeds take longer to mature.

At What Age Are Ferrets Full Grown?

Ferrets are usually full-grown at four months. The most common growth spurts for a ferret happen around the first three months of age, then again at six to nine months.

However, some breeds take longer to reach maturity, so it’s possible your female could still have growing left!

If you have any questions about your ferret’s development and how big they will get or when they stop growing, let me know in the comments below!

You should talk with your veterinarian about any concerns you might have about your pet’s development!

How Big Do Ferrets Grow?

The average Ferret is about 12 inches in length and weighs about four to seven pounds. Smaller animals are more common if you get them from some farm because they have been spay/ neutered early at eight weeks of age!

If you get your ferret from a breeder, it may grow to be bigger than the average size.

In the United States, ferrets are second only to cats in popularity as pets. The most common breeds of ferret available for purchase are Bulldog Ferrets and Greyhound Ferrets. Whipped-Ferret Body Types are popular with people who do not want a pet that is too big for their living space or handling limitations.

What is the Typical Weight for an Adult Ferret?

The normal range is about four and seven pounds in weight but can vary from three to eleven pounds depending on how big your individual animal grows.

How Old Does a Ferret Have to Be to Stop Growing?

Ferrets grow to their full size in their first four months. Male ferrets, or hobs, weigh about 2.5 pounds. Females, or jills, are considerably smaller, weighing about 1.5 pounds.

Even though all ferrets descend from one European breed, they evolved into three different sizes – Bulldog, Greyhound, and Whippet.

Bulldog Ferret

The bulldog ferret is, as its name implies, stockier and shorter than the other two types. It has a “bulldog” like face and, in general, is heavier in the front than in the back.

Greyhound Ferret

The Greyhound ferret is an elongated version of its ferret cousins, with a slender face and smaller head. The Greyhound Ferrets shape makes them appear more like Weasels than their shorter cousins in comparison.

The Greyhound Ferret Body Type is also long and slender.

Whippet Ferret

The whipped Ferrets are the smallest of the three ferret body types. They have a slender body with a very narrow face that looks almost like it has been stretched in an oval shape. And they are the most agile of the three types.

How Long Does a Ferret Live?

The average life span for a ferret in the wild is about three years. Domestic Ferrets live an average of eight or nine years, with some living up to 12-15 years old and even longer! But this is heavily dependent on where you got your ferret from.

Ferrets bought in pet stores have a shorter lifespan than ferrets bought from a reputable breeder.

A group of ferrets is called a “business.” Named after their Latin name Mustela putorius furo, these animals originated from Europe. They were domesticated more than two thousand ago by European farmers who used them as working pets on farms because they hunt rodents such as rats mice that can damage crops.


Ferrets grow the most until they are four months old. The maximum is reached somewhere around month six. No matter how big your ferret is, they will always be your best friend.

Ferrets are playful animals who love to explore and learn! They have a reputation for being mischievous and sneaky because of their ability to squeeze through tight spaces that other animals cannot get into.

Ferrets also use this skill to escape from cages or pet carriers if given a chance…

If you’re thinking about getting a ferret as your next furry companion, make sure it’s legal where you live first before investing any money on one. Make an informed decision by researching these creatures beforehand so you can keep your ferret forever.
