What Do Chinchillas Eat in the Wild and as Pets?

In the wild, chinchillas are omnivores, which means that they eat both plants and meat. However, they eat mostly vegetation and seeds. Occasionally, they will eat insects and bird eggs. This only happens opportunistically, though. They won’t go hunting for insects, but if they see one, they will eat it. They eat all sorts of different plants in their native area, including shrubs, grasses, flowers, and roots.

They are also known for eating bark, which is very high in fiber. For this reason, they need a high amount of fiber in captivity as well.

As you might imagine, their diet varies a bit when they are domesticated. They don’t have control over their own diet and rely completely on their owners for sustenance.

They will require mostly good-quality hay. In the wild, they eat mostly grasses, so hay is a suitable alternative when they are domesticated. They will also eat grasses, leaves, and twigs, but these are harder to provide safely in captivity. Most grasses in suburban areas have been treated with dangerous chemicals that will hurt chinchillas. Therefore, only hay and grasses specifically set aside for Chinchillas should be used.

On top of this, chinchillas should also be fed appropriate pellets. These provide some added nutrients and vitamins that they may not get from the hay. They can be fed dried fruits and root vegetables as treats. Assorted herbs can also be given. However, these should only be provided as treats, as they can cause the chinchilla to become overweight.


What Fruits and Vegetables Can Chinchillas Eat?

Chinchillas can eat a wide variety of veggies and fruit. However, some can be given more than others. It largely depends on the nutritional value of the fruits, as well as how sugary it is. Generally, you want to provide the most nutrition per calorie.

These veggies can be provided regularly:
  • Alfalfa
  • Celery
  • Potato
  • Carrot
  • Kale
  • Sweet Potatoes
  • Squash

Fruits that are high in sugar should only be fed occasionally, including apples and most berries. These are simply too calorie-dense without offering increased nutrition. Therefore, they may cause nutritional deficiencies if they are fed too much of these fruits. They can also cause obesity due to the high amount of sugar.

Where Can You Purchase Chinchilla Food?

You can purchase suitable hay from nearly any pet store. If the store carries other small pet supplies, they will likely have some sort of appropriate hay. These stores will often have pellets as well. However, this is a bit rarer than hay. You may have to order pellets online, as not all stores carry them.

Veggies and fruits can be purchased from the store. Human-grade fruits and veggies are perfectly fine. Many people use scraps from their own supply of vegetables and fruits since these chinchillas often eat very little. They aren’t going to eat a whole pack of celery.

Can Chinchillas Eat Rabbit Food? Or Other Rodent Food?

Chinchillas aren’t kept as pets as often as other rodents, such as mice and rabbits. For this reason, it may be tempting to buy food designed for these other animals, as it is often easier to find.

Chinchillas can eat some foods designed for these other rodents. For instance, hay is usually pretty universal. You don’t have to purchase species-specific hays. These hays are sometimes advertised for specific species, even though hay is hay.

However, you must purchase pellets that are specific for chinchillas. They need specific vitamins and minerals, which species-specific pellets will provide. However, pellets designed for other species will not meet these requirements. They may have too much of a specific nutrient and not enough of another. It is important for the pellets to be specifically designed for the chinchillas.

Do Chinchillas Eat Other Animals?

No. Chinchillas are omnivores by classification. However, they eat insects—not other animals. They may occasionally eat a bird egg or two, but these are eggs that they happen to come across while foraging. They will not purposefully hunt down bird eggs or insects. They’re opportunistic eaters.

Meat does not make up a core part of their diet. However, they may happen to eat meat that they come across, which makes them an omnivore. For the most part, chinchillas will eat grasses and similar vegetation.

What Is a Chinchilla’s Favorite Food?

A chinchilla’s favorite food is going to vary from individual to individual. While these animals do all have the same general diet, they do have their own preferences. It is important to point out that their favorite foods typically aren’t things that they can have very often. Chinchillas tend to like fatty or high-carb foods.

From a survival perspective, this makes sense. You want to eat the most calorie-rich items, as these will keep you alive for longer than low-calorie items. However, a diet that only consists of high-calorie items is bound to lead to obesity. Furthermore, many of these high-calorie items are not nutrient-dense, so they can lead to nutrient deficiencies if it is all your chinchilla is eating.

You’ll have to figure out your chinchilla’s favorite food based on experimentation. Simply try a few different treats and see what they prefer. Of course, don’t just give them their favorite food all the time, but you can use them as an occasional treat.

How Often Do Wild Chinchillas Eat?

Chinchillas in the wild usually eat twice a day—in the morning and in the evening. Like rabbits, they usually come out during low-light times. This is when they can see enough to carefully find appropriate foods, but when it isn’t so visible that they may be taken off by a bird or similar predator.

However, unlike many other rodents, they may consume food throughout the day. They eat somewhat slowly, so they may not be able to consume all of their necessary food during this time.

Pets can be offered a similar amount of food. They should be offered food twice a day, but hay should generally be provided all the time. They typically won’t overeat hay, and it provides them with an opportunity to wear down their teeth.

Can Chinchillas Eat Cheerios?

Yes, in moderation. Like most treats, chinchillas can eat a few Cheerios. They will not hurt them and are non-toxic. However, they don’t exactly contain all of the nutrients that a chinchilla needs, so they should not take up the majority of a chinchilla’s diet. (Or even any measurable percentage of their diet.)

Cheerios also have an incorrect calcium-phosphorus ratio. If your chinchilla eats too much of them, they can develop an imbalance. This can cause all sorts of problems.

Many chinchillas do like Cheerios, so they can make a good treat. They are also inexpensive. Of course, be sure to get regular Cheerios, as many of the flavors have lots of added sugar that can upset their diet. You just want the plain ones.

What Foods Are Bad for Chinchillas?

There is a long list of food that chinchillas can’t eat. As you might imagine, you shouldn’t give your chinchilla anything that doesn’t fall into the fruit or vegetable category. Dairy, meats, and similar foods should be avoided. These aren’t a part of their natural diet, and they do not have the enzymes to break them down properly. This can upset their stomach and cause health problems.

There are also types of fruits and vegetables that they cannot eat.

For instance, you should avoid:
  • Asparagus
  • Avocado
  • Peas
  • Cabbage
  • Corn
  • Lettuce
  • Broccoli
  • Spinach
  • Rhubarb (and leaves)

You should also avoid high-fat nuts and seeds, including sunflower seeds and peanuts. While these animals may eat low amounts of seeds in the wild, these are typically not fatty like sunflower seeds. Very sugary fruits should be avoided as well, such as strawberries and bananas. Look for low-calorie, high-nutrient foods.

The calcium-phosphorus ratio is also important. An imbalance can be caused easily by the wrong diet, which can cause all sorts of health issues. For this reason, it is best to stick to a shortlist of safe foods and only feed treats very occasionally.



In the wild, chinchillas mostly eat grasses and other vegetation. They are similar to rabbits in this manner. They may occasionally eat an insect, but this is usually an opportunistic eating pattern. If a bug happens to be in front of them, they will eat it. However, they won’t go out and search for them.

While in captivity, the easiest way to mirror this diet is by providing plenty of hay. The hay also wears their teeth down, which is important for their overall health. They can also be provided with a few safe veggies and fruits for some extra nutrition. Pellets should be provided, as they are fortified with nutrients as well.
