How to Stop Hamsters From Biting?

Exploring the world of hamsters is captivating – their small paws and curious eyes are truly charming. However, these adorable creatures sometimes display puzzling behavior, including biting, which can make us a little worried.

Hamsters may bite for reasons like seeking attention, alleviating boredom, managing teeth growth, or exploring their chewing instincts. Such bites can disrupt peace and potentially harm the hamster’s mouth. To prevent this, let’s explore how to stop hamsters from biting.

Understanding why your hamster bites is the first step toward curbing this undesirable behavior. You can also discourage this behavior by getting a larger cage and providing chew toys to your hamster.

But that’s not all. Read on to discover how you can keep your hamster from biting.

Why Do Hamsters Bite?

Small cage

This is a big problem since many hamsters are kept in small cages. Hamsters need more space to be happy and healthy because they’re used to exploring and digging in the wild.

Small cages can make them feel stressed and bored, leading to unwanted behaviors like biting. Providing a larger cage with toys and tunnels gives them room to play and be themselves, preventing biting and ensuring their well-being.

Teeth growing

Hamsters have teeth that keep growing, so they need to chew and nibble on things constantly.


Anxiety can trigger hamsters to resort to biting as a form of response. When hamsters feel stressed or fearful, they might become more likely to bite as a way to protect themselves or communicate their discomfort.

Maintaining a clean cage is essential for hamsters, as they prefer tidy surroundings that help prevent anxiety. Additionally, providing a proper diet is crucial to prevent potential psychological issues.

Recognizing and addressing the sources of anxiety in a hamster’s environment can be crucial in preventing this behavior and fostering a calmer and more harmonious relationship with these small companions.

Depression and Boredom

Living in a cramped cage without activities or toys can lead to hamster depression. They need enrichment and exciting toys to stay happy. Loneliness and boredom can also cause depression, leading them to bite the cage out of frustration.

Introducing a hamster wheel and chew toys can provide entertainment and alleviate such behaviors. Learn more about stopping cage biting here.

Let Your Hamster Get Used to You

In the evening, when your hamster is active, spend some time near the cage and talk to your hamster. You can read or even sing to your hamster if you don’t know what to say. The idea is to let your furry friend adjust to your presence, scent, and your voice.

Remember, moving to a new cage is very stressful, so let your hamster adjust to life in its new home. At this point, don’t try to touch your pet hamster, or he’ll bite you.

Let Your Hamster Get Used to Your Scent

Gently place your hand inside the cage and let your hamster sniff your hand. Remember to move very slowly. Any abrupt hand movements may scare your hamster. On the first day, put your hand just inside the door. Don’t touch your hamster, but slowly put your hand in a little farther. If your hamster becomes curious, let it explore your hand.

Offer Your Hamster Treats

You may need to discover your hamster’s favorite treats through trial and error. Try giving your hamster healthy snacks like sunflower seeds, raisins, and apples. These treats can also be great training tools.

Use your bare hand to offer your hamster these treats. Eventually, it will associate you with treats and will develop trust. Keep your hamster from biting by gaining his trust. If you want to prevent attention-seeking biting behavior, you’ll need to spend more time with your hamster.

Pet Your Hamster

Once your hamster is at ease with taking treats, you can start gently petting it. Gradually, if your hamster remains calm, you can progress to picking it up. Should your hamster bite, maintain patience and persistently offer treats to build trust.

Pick Up Your Hamster

When your hamster is comfortable with treats, proceed to pick it up gently. Allow your hamster’s reaction to guide the pace of each session. One technique is using treats to coax your hamster onto your hands.

Gradually scoop your hamster up with both hands, ensuring a gentle hold without gripping tightly over its back. This is important, as pressure on their back can make them feel threatened. Beware that some hamsters might attempt to jump, so avoid holding them high off the ground.

Give Your Hamster a Bigger Cage

It’s possible that your hamster is bored and longs for more room to play in his cage. Your hamster might express boredom by biting cage bars. Providing them with a larger can be the solution to this problem.

As a general rule, a hamster needs at least one cubic foot of space.

Offering dog treats to your hamster can be a fun variation. Hard biscuits can serve as excellent chew toys. However, limit hard treats to about once a week. While providing treats, ensure they are garlic-free, as garlic can lead to digestive issues for hamsters.

Give Your Hamster a Cardboard

The cardboard tube from a toilet paper roll or paper towel makes a great chew toy for hamsters. Additionally, it provides a fun hiding place for your hamster.


Entertained and happy hamsters seldom bite.

Give More Playtime and Exercise

Increase quality time with your hamster to curb attention-seeking biting. Allow supervised roaming on your bed or in a hamster-proof room to counteract boredom.

An exercise ball provides exercise and safety, but watch for overheating and limit play to 15 minutes. Ensure the room is safe by removing cables and using barriers. A hamster wheel is another exercise option; avoid wire frames to prevent injury.

Hamsters need plenty of playtime and exercise. When you apply these methods, your hamster won’t feel abandoned and won’t bite you.

Spend One-on-One Time

Hamsters thrive on social interaction and need regular one-on-one time with their owners for emotional well-being. Spending more time with your hamster helps prevent attention-seeking biting. You can hold your hamster outside the cage or let them explore on your lap.

Use a small box to gently remove them from the cage, avoiding scaring them by reaching in directly. Lying on the floor allows your hamster to crawl on you, fostering trust and a desire to explore.

Let Your Hamster Sleep During the Day

Hamsters are nocturnal creatures, which means they sleep during the day and are awake at night. Waking your hamster up during the day to play or clean his cage may irritate him. Interrupting his natural sleep routine will worsen his biting behavior. So, it’s important to let your hamster sleep during the day.

Consult the Vet

If your hamster’s teeth haven’t responded to chew toys, a vet can trim them to a suitable length. This quick procedure doesn’t harm your hamster. Always consult your vet before attempting any tooth-trimming at home.

  1. I adopted a hamster that was totally hostile. She has a very large cage, with lots of toys and places to explore, hide and dig. She has lots of room to run, as well as a wheel, which she does use. I clean her cage very regularly. However she still bit whenever my hand was near her. She would try to bite the scoop as l was cleaning her litter. One day, while singing to her, l trailed a piece of tissue across her head, basically caressed her head with it. She stood completely still and let me do it again. She closes her eyes and looks like she is savouring the experience. Eventually with the back of my finger, l could gently caress her ears and face, and the length of her. Several times l have been able to scoop and hold her….sometimes with her favourite foods in my hand…chia seeds, hemp hearts, sesame seeds. She has required a lot of time and patience, but she is becoming a friendly little girl.
