How Much Do Chinchilla’s Weigh? [Optimal Weight and Advice]

When I first adopted my chinchilla I had a simple question come to mind. How much do chinchillas weigh?

I have now been raising my chinchilla for more than 5 years and here is what I can tell you on this topic.

So, how much do chinchilla’s weigh? Chinchilla’s weigh between 400-600 grams. This equals 8/10ths of a pound. A healthy chinchilla after they mature will weigh closer to 600 grams or 1 pound. Chinchilla’s should not exceed 600-700 grams to remain at a healthy weight and optimal health.

While these are the ideal weights you should be striving for with your chinchilla, it’s much easier to obtain these weights with minimal work if you don’t overdo certain things and keep your chinchilla on a healthy diet.

If you stick around for 2-3 minutes and join me for a few tips, I will ensure you know the best practices to ensure your chinchilla remains in this window and at the ideal weight to live long and healthy lives.

Weighing Your Chinchilla Is The Best Approach

This may come as a big shock to you, and I know that many chinchilla owners don’t do this, but the best practice is actually to weigh your chinchilla on a weekly or monthly basis.

Due to a chinchilla having such dense fur and being such a small rodent, it’s sometimes hard to notice when a change occurs.

Weighing your chinchilla will allow you to track changes much more easily.


This can be done easily by purchasing a cheap scale and merely performing a weight check during their time out of the cage.

If your chinchilla isn’t a huge fan of being held, you may have to get more creative with this process.

Overall, it doesn’t take long for your chinchilla to get warmed up to you, and you likely won’t have any issues with this task.

This is a simple precautionary step you can take to ensuring your chinchilla is eating and gaining weight accordingly.

This is especially important if you have a newborn chin that needs more TLC and tracking to ensure they are progressing healthily. Again, I’m aware that many chinchilla owners don’t currently do this, but if you want to worry a bit less about your chinchilla, this is an excellent way to stay on top of things.

Stick to The Correct Diet for Your Chinchilla

This is as easy as it can get. Having your chinchilla stick to the correct diet will help your chinchilla remain at the proper weight with ease.

If you are unsure what foods your chinchilla should be eating, you can start by reading my full guide on what chinchillas can eat here.

It will give you a full breakdown.

Not allowing your chinchilla to eat treats or foods in general that are high in sugar is one of the most critical factors.

Additionally, you need to be offering your chinchilla specially formulated pellets in addition to timothy hay as their two primary food sources.

This advice alone is going to help you dramatically to keeping your chinchilla at ideal and healthy weights.

Don’t Go Overboard Offering Your Chinchilla Treats

While this may sound easy, it’s likely one of the most challenging things you can do.

With how affectionate a chinchilla can be towards you, it’s tough not to get in the mood to offer an award a bit too often or more than we should.

However, you need to be aware that doing so is dangerous to your chinchilla’s health.

I read a lot of forums and posts where chinchilla owners get a bit crazy with treats.

Especially in the form of fruit. Sadly, not all the treats are even considered safe in your chinchilla.

I also have a post about what fruits your chinchilla can eat and which they can’t that you can see here.

I believed this was an important and crucial topic to discuss, and I think that this post may be able to help you greatly towards owning and raising a chinchilla to live healthily and at the correct weights.

Ensure You Understand What Treats You Should Offer Your Chinchilla

I already briefly touched on this, but some chinchilla owners also offer their furry friends more than just the fruits we mentioned before.

I recommend always learning from a reputable source or even speaking to a vet if you believe a treat may not be safe or if your chinchilla may be showing signs of weight issues.

I personally am not a huge fan of offering my chinchilla too many treats and try to stick to nothing, but chinchilla formulated pellets, timothy hay, and chew sticks.

Outside of this, I may offer my chinchilla oats occasionally and nothing much else.

I haven’t encountered an issue thus far with any illnesses with my chinchilla nor had any problems with my chinchillas’ weight, so I think this is the most straightforward way to ensure your chinchilla maintains healthy weights and stays free some digestive, stomach, and other health concerns.

Ensure Your Chinchilla Is Active During Playtime and Has Space to In Their Cage

Activity is a way we all stay in shape and keep our weight in check, right? Well, the same can apply to your chinchilla.

I think all of you know if you follow my blog at all that I always recommend an adequately sized chinchilla cage.

If you weren’t aware of this, read my post about the proper size of chinchilla cages here.

It’s imperative that your chinchillas can act like chinchillas.

This involves running around as well as getting crazy jumping from shelf to shelf.

Not only that but chinchillas love to climb and interact inside of their environments.

A big cage with multiple levels can help your chinchilla to remain active, healthy, and happy.

In return, your chinchilla should be able to stay at a healthy weight and keep their bodies at peak performance.

While the cage size is important, it’s equally vital that you ensure that you are getting your chinchilla out of the cage to run around and burn off some energy at least once per day.

This is another way to keep your chinchilla mentally stimulated, active, and can help to keep their weight in check.

It’s like all other animals and even us as humans.

We consume calories, but the more activity and the more we do in general helps to burn some of that weight and keep us stronger and healthier.

Understand When to Contact Your Vet If You Sense A Problem

Now, let’s assume that you have done everything correctly. Let’s also assume you aren’t overdoing any treats or other advice against practices.

If your chinchilla still appears to be gaining weight, bloating or something seems off in general, you need to recognize when it’s time to call a Vet and allow them to help.

Additionally, it’s imperative that you are working with a vet that knows and understands chinchillas.

While chinchillas are relatively popular pets and wonderful pets to own, not all vets are knowledgeable about how to help and treat a chinchilla.

Do your homework and diligence ahead of time, so you aren’t stuck in a pickle when something does go wrong or pops up.

Long story short, you need to be aware when you can’t help or remedy the problem, bust out the wallet, and be prepared to head into your local vet.

Doing so is the best way to ensure your chinchilla remains safe and healthy and your chinchillas’ weight is an integral part of their health as many other animals and even us as humans.

While Chinchillas Have an Ideal Weight, It’s Easy to Maintain

While this post may have scared you a bit about the challenges that could arise owning a chinchilla, it really shouldn’t have.

It’s straightforward to keep your chinchilla healthy and happy.

Refrain from too many treats and be sure only to feed your chinchilla food that’s deemed safe.

Additionally, always be alert and understand when it’s time to let a professional help you.

A chinchilla’s weight is certainly essential to keep tabs on but nothing to get overly anxious about.

Most chinchilla owners honestly will never even encounter an issue with this, but in case you do, I hope this post helped.

Chili and I wish you the best of luck with your new chinchillas and the journey you have ahead of you.
