Male vs Female Chinchilla

So, you’re just about to adopt a pet chinchilla, and that’s marvelous! Chinchillas are good-natured and love spending time with one another and with their owners.

But you now have the most important decision to make.

Should you get a male or female chinchilla?

Up next, we are going to have a look at all of the differences between a male and female chinchilla to help you decide which will be best for you.

Let’s get comparing!


For our first comparison, we are going to take a look at the size difference between male and female chinchillas. This will help you choose the right size enclosure for your pet rodent that will meet its needs.

What size are chinchillas?

A female chinchilla in captivity tends to be about 30% larger than a male. However, the size difference between the two sexes is much more obvious in domestic chinchillas than it is in wild chinchillas.

Pet chinchillas are normally almost double the size of those in the wild. Chinchillas need large enclosures to feel comfortable in captivity.

If you choose a female chinchilla, be aware that it will grow to be much larger than the male.


Another area in which male and female chinchillas differ is their weight.

How much do they weigh?

Long-tailed chinchillas in captivity weigh a lot more than wild chinchillas. The females, for example, weigh up to 800 g in captivity but only up to 450 g in the wild.

Male long-tailed chinchillas in captivity weigh up to 600 g but only up to 493 g in the wild.

Regardless of their weights in the wild and in captivity, you will have already noticed something interesting. Yes, female chinchillas are heavier than males!

If you choose a female chinchilla, be aware that it will be slightly heavier than the male.


Many people wonder whether the sex of the chinchilla changes its nature and how well it will get on with its owner and other chinchillas.

Can male and female chinchillas be kept together?

Chinchillas are good-natured, and both males and females tend to be very social creatures. In the wild, they live together in groups of up to 100 members called herds.

A male chinchilla can live with a female and they will get on very well together.

The only time when female chinchillas become more aggressive is during estrus. At this time, females will show aggression towards one another and to any males in the enclosure.

Although female chinchillas can act aggressively at this time, serious fighting is extremely rare between them.

Both male and female chinchillas are good-natured animals, but the females can act aggressively during estrus.

Cage Mates

If you would like to house more than one chinchilla, you must make sure that they will all get along. You want cage mates that complement one another, as chinchillas like to be in one another’s company.

Which gender groups are most successful?

A female chinchilla can live with other females and with males and get on very well. Small groups of chinchillas are best because they like to spend time with one another.

It is best to always have at least two chinchillas living together, such as two females, two males, or a neutered male and a female, so they do not get lonely.

A male chinchilla can live with other males and with females. But you should never put groups of mixed genders together unless the males have been neutered.

While it is possible for you to neuter females, this is less common.

Even after passing sexual maturity, your chinchillas will continue to get along while living in the same cage. If you want to introduce a chinchilla of either gender into the cage, you’ll need to act with caution.

Chinchillas are often aggressive and territorial with those they don’t know. To prevent aggression, keep the chinchillas in separate enclosures to begin with and allow them to play with one another while you supervise them.

Once the animals get used to one another and no longer show signs of aggression, move them into the same cage.

Small groups of males and females work well, but you must introduce new chinchillas into the cage gradually.


Male and female chinchillas reach sexual maturity at 8 months old. After that, mature females can become pregnant and give birth to one or two chinchilla babies called kits.

How do both female and male chinchillas take part in parenting?

Females will look after their kits and keep them warm when they are born. In the wild, she will go and look for food for the kits to eat.

If a female cannot produce milk for her kits, other females that are lactating will take over the role of feeding the young.

Males will also have an active role in looking after the kits, unlike in other rodents. They will keep them warm when they are born and will take care of them while the mother is away looking for food.

Both males and females play important roles in bringing up kits.


Chinchillas are exotic pets that are native to South America. If you’re keeping chinchillas for the first time, you’re no doubt intrigued to find out their correct names.

What is a female chinchilla called?

What is a male chinchilla called?

When you get your chinchilla home from the breeder or pet shop, you might want to check which sex your new pet is.

But what if you’re not sure how to tell if a chinchilla is male or female?

Female chinchillas do not have a gap between the urethra and the anus. Males, on the other hand, do have a gap.
