Do Chinchillas Have Periods? [How It Actually Works]

If the first chinchilla you adopted is a female chinchilla like me, you likely have some questions about a female chinchilla in heat or if female chinchillas have a period.

Especially if you plan to breed or have multiple chinchillas sharing a cage that has bonded.

Do chinchillas have periods?

I have been raising a chinchilla for the past 5 years and here is what I can tell you.

No, chinchillas do not have periods. Chinchillas do go into heat when they are more likely to mate and have the capabilities of reproducing. This is known as the oestrus cycle and lasts 28 days but a female chinchilla will only be in heat for 2 days.

I know, trust me.

When I adopted my 1-year old chinchilla, I got home and realized that was a question I completely forgot to ask.

Here is how I intend on breaking down the rest of this brief post for you today.

Do Chinchillas Have Periods Female Chinchillas In Heat

Alright, like I said before.

Breathe easy.

Your chinchilla will not bleed or have a typical period that may come to mind.

Chinchillas are unique in the sense that they can breed any time of the year but they are more prone to breed during certain months and seasons.

Typically from November until March is relatively common.

Female chinchillas also have the unique abilities to throw you for a loop when it comes to being in heat.

They don’t display any physical or behavior signals that they are in heat which can easily throw you off some.

To notice any behavior shift when a chinchilla enters heat, you will typically notice a chinchilla acting more cranky than usual or they may be easily agitated during this phase.

However, since many chinchillas are timid a majority of the time, this can be tough to notice like mentioned previously.

Especially if you are a breeder or looking into becoming one.

You Won’t Recognize Chinchillas Are in Heat Most Of The Time

Let me re-emphasize where I was at in this post a moment ago.

It’s going to be very difficult for you to recognize your chinchilla is in heat.

Most chinchilla owners, including myself, state that the only behavior change they notice is increased energy or a chinchilla that is slightly more irritated than usual.

No other physical signs will be present or displayed by your chinchilla during this time.

If you have two chinchillas, it’s much easier to recognize this behavior in a fast fashion.

Most of the time, if your chinchilla is in heat, they will enjoy a nice game of “cat and mouse” with the other chinchilla.

Female chinchillas like to play hard to get when they are in heat and allow the male chinchilla to chase them around endlessly.

These darn chinchillas are much more human-like than we like to admit.

Probably one of the reasons I think they are such fantastic and unique pets to own and care for.

If you don’t have two chinchillas, you will have to plan on looking for visual signs that your female has more energy.

However, the chase game is usually a sure-fire way to know that some baby chinchillas may be in your immediate future.

Male Chinchillas Will Discharge a Waxy Substance During Breeding

Another easy indicator to know if your chinchilla is in heat is to look for a waxy substance inside of the cage.

This will be discharged by the male chinchilla and helps the male chinchilla keep semen inside of the female chinchilla.

Simply noticing some of this waxy substance inside of the cage is a definitive answer for you and a quick way for you to realize if your chinchilla is in heat or not.

Do Chinchillas Go into Heat?

Yes, chinchillas go into heat but they do not have periods.

Using some of the previously mentioned observation methods is going to be your number 1 indicator to recognize if you have a female chinchilla that’s in heat or not.

You can also try and watch for your male and female chinchilla having intercourse.

If this is taking place, your female chinchilla is 100% in heat, and the potential for some chinchilla off-spring is right around the corner for you.

This leads us into the next important part of this post, which will cover what you can expect after this has taken place and your female chinchilla is pregnant.

How Many Babies Do Chinchillas Have?

If your female chinchilla is at least 8 months old, you have a female chinchilla that’s capable of becoming pregnant and is now considered “sexually active.”

Depending on where you are located, will determine when the most likely mating season for your chinchillas.

In most circumstances, the mating season for a chinchilla is going to be between November and May of each year.

Male chinchillas will attempt to perform intercourse over different periods, which can either result in a receptive female chinchilla, or the female chinchilla may show some aggression if she is not in heat or ready to mate.

Once your chinchilla is in fact, pregnant, you have a long gestation period ahead of you.

Chinchilla has a gestation period of 110 days.

When this gestation period is over, the baby chinchillas will be born 1 at a time and usually only a few minutes apart.

Chinchillas have 2 baby chinchillas for each pregnancy most of the time.

However, it is possible that your chinchilla gives birth to up to 6 baby chinchillas during one pregnancy.

This is more rare than typical, and two baby chinchillas are what most chinchilla breeders will advise you is common.

What to Expect When the Baby Chinchillas Arrive

At this point, we are already aware that your chinchilla is going to have 2-6 baby chinchillas with the most likely scenario being 2 baby chinchillas.

When the baby chinchillas are born, they will weigh roughly 2 ounces each and are fully active after birth.

Something to keep in mind during this phase of the life cycle is to ensure you separate the mother chinchilla and have her isolated in her own adequate size cage with just her babies.

You can see my post about the best chinchilla cages here for further information.

You don’t want or need the male chinchilla present during this time.

The female chinchilla is going to be protective like most animals are of her new offspring and are the primary caregiver to help the baby chinchillas remain warm.

Also to supply the baby chinchillas with milk and protect them until they can handle themselves which takes about 7 days or one week.

After this one week has passed, your baby chinchillas will now be able to consume regular hard food and won’t be so dependent on the mother chinchilla for protection and milk.

Although the protection and dependency have decreased after the 7-day mark.

You should still expect your baby chinchilla to depend on their mother for up to 8 weeks until they are fully ready to fin for themselves.

Female Chinchillas Do Go into Heat But Do Not Have Periods

As mentioned throughout this post, yes, a chinchilla does technically have a heat cycle but it is short-lived and hard to notice a majority of the time.

If you currently only own one chinchilla or house your chinchillas in separate cages, this isn’t nearly as much of a concern for you as other potentially reading this post.

However, if you do have a male and female chinchilla together, it’s very likely your female chinchilla will be pregnant sooner or later.

Using the tips laid out in this post should help you to remain prepared and understand what’s to come.

Breeding chinchillas can be a fantastic way to go about things if you know what to expect and can do so in an ethical manner.

I’d love to hear all your feedback on this topic as well.
