The domestic chinchillas are curious and adorable animals at the same time. They originated from the hybrid breeding of short- and long-tailed chinchillas present in the wild. These social and friendly cuties are native to the Andes Mountains range and are protected by the government from illegal hunting and poaching.

Many ambiguities are roaming around your mind if you are planning to keep a pet chinchilla. One of the important questions is about the temperament and aggressive behavior of your new pet. You’ll be pleased to know that chinchillas have a very calm and placid personality. They don’t show any aggression and biting behavior unless they are mishandled, stressed, or scared.

Are Chinchillas Aggressive?

Among the personality traits of chinchillas, they are masters at adapting to new habits and environments. These furry animals have a high IQ and extremely social temperament. They stay outgoing and comfortable unless provoked by stressful actions by owners. These traits make chinchillas quite fantastic and unique in terms of loving pets.

Aggression and Biting Behavior of Chinchillas

No matter if you already have a chinchilla or you’re planning to get one, you must always take care of his or her comfort levels. Although chinchillas are quite loving and super-friendly pets to keep, they may show aggressive behavior like other animals. It is always ideal to monitor and look for potential signs of aggression.

When chinchillas are uncomfortable with their owners, they show altered body language. They may try to get away from you or stand with face and ears alert towards you. Making grunting sounds is quite common if your pet appears nervous. They may corner themselves and show aggression when you try to pick them in your hands.

Causes of Aggression in Chinchillas

The foremost and important reason that your chinchilla stops showing interest in your cuddles is fear. These animals are very sensitive and get scared by sudden and abrupt activities.

If you get close to him quickly, your beloved pet gets startled and scared. Additionally, loud noises such as thundering & honking horns also lead to irritation and aggression in chinchillas.

Chinchillas show biting behavior in aggression and that is quite different from nibbling. Nibbling is an instinct due to their poor eyesight and grooming behavior.

Biting, on the other hand, is a prominent sign of aggression and discomfort. These bites are quite painful in my opinion as these animals can chomp down anything they bite.

Another important reason for aggression in your chinchilla is faulty management. Chinchillas like to roam and play due to their climbing behavior.

Compromised spaces such as small cages and overcrowding can result in the development of irritation. Housing too many chinchillas in a single cage are not recommended by animal healthcare experts.

The disease conditions and sickness can result in stress and seclusion in chinchillas. In illness, you may find your chinchilla not interested in daily activities. He or she doesn’t move around so much and spends most of their time in a cage or a silent place.

Other managemental issues that may lead to an aggressive attitude in chinchillas include too hot or cold temperatures and abrupt loud noises.

As these animals are crepuscular, they get scared and stressed by bright, flashy lights easily. Therefore, it is always necessary to closely monitor the possible aggression causes for an efficient solution to the underlying problem.

Chinchilla’s Aggression & Your Role

The solution to your chinchilla’s peace lies in eliminating the cause of his or her stress. Animal experts always recommend close monitoring of chinchilla’s behavior and management.

The most compulsory thing to do is to make sure your chinchilla lives in a peaceful and comfortable environment. This can be ensured by providing ample and protected space with all the things chinchilla needs to feel like at home.

Loud and continuous noises act as the main source of developing aggression and irritation in chinchillas. As a veterinarian, I recommend you to get your beloved pet accustomed to the usual sounds at your home. You can do that by holding your chinchilla close to yourself in an assuring and comfortable way. 

Make some room for your furry friend by providing him or her with adequate space. The spacing requirements of the cages must be done such that your pet can eat, sleep, play and rest. Even if you want to keep more than one chinchilla, there must be ample space and toys for them. Always respect chinchilla’s boundaries and handle them gently and softly.

Another valuable suggestion is to avoid such activities your chinchilla doesn’t like. Many people try to chase them around the house or in their cages.

Besides, owners having less knowledge about their behaviors force them to try disliking things. Such activities lead to irritation, exertion, and stress in chinchillas. Always try to give them enough adjustment time if you bring them to your home recently.


Chinchillas are loving, calm, and friendly social cuties you can keep as pets. Aggression in chinchillas is an uncommon thing and only occurs when they are provoked or under stress. If your chinchilla is showing aggressive behavior and won’t stop biting you, don’t worry and try to bond again.

It is always ideal to give your chinchilla plenty of comfortable space and time to help them get playful and happy. As a veterinarian, I recommend you to use treats every time your chinchilla wants to get playful and cuddly with you.
