It’s annoying to see hamsters biting each other. What to do when hamsters bite each other? How do you know when hamsters are biting each other and when they’re just enjoying playing?

In this article, we’ll learn about the signs and risks of hamster bites and injuries such as bleeding

Why do hamsters bite each other?

If you decide to get a hamster bear, they should always be kept in separate cages. Bear hamsters are cute to play with, but they are very territorial in their own space.

Therefore, bear hamsters need to be housed separately from about six to eight weeks of age, at which point they should not be kept together.

The most common reasons hamsters bite each other are because they have limited space, feel threatened, or are stressed by a shared cage partner.

However, most hamsters are of a breed that happily shares their home as long as they are kept of the same breed but of different sexes.

What to do if hamsters bite each other?

Hamsters may not always fight, and bickering, fighting, and fighting are not uncommon, but importantly, these disputes are usually not dangerous, which can happen when hamsters are still getting to know each other.

You only need to worry when they are chasing each other and hear hissing and squeaking, but this is not a 100% accurate warning sign that your hamsters are about to fight.

In the case of two hamsters fighting each other, the other thing is not fighting but grooming each other. While squashed hamsters usually squeal in this situation, it’s a sign of dominance rather than an actual fight.

If you’re wondering if your hamsters are actually fighting, pay attention to how they interact each day and look for injuries. If your pets get along well, they will usually share activities like sleeping, eating, and grooming.

What to do if hamsters bite each other and bleed?

Hamsters may look small, but they are very aggressive, and a fight between two hamsters is usually not for the faint of heart.

Hamsters often attack with their teeth, so hamsters attacking each other’s teeth can cause serious injuries, causing each other to bleed, and even if you don’t stop them in time, hamsters can bite each other to death.

Therefore, it is important that if you see two hamsters biting each other, you step in and separate them as soon as possible. However, separating two hamsters in a fight is much easier said than done because they can bite you too if you’re not careful.

Therefore, we recommend wearing gloves or trying to place a barrier between each hamster so you can safely separate them once they have calmed down.

Note that once the hamsters bite each other, it is difficult for them to live together again, so each hamster should be kept in a separate cage.

How to keep hamsters from biting each other

If you decide to keep two hamsters together, there are a few things you can do to promote harmony between the hamsters:

As we all know, female hamsters like to be with other people, while male hamsters will live happily alone, and mixing hamster sex will only lead to hamsters biting each other, which is inevitable. Regardless of gender, you should never keep two hamster bears together as they are solitary pets and need to live alone.

Slowly introduce the hamster

Every hamster has its own personality. So never put two hamsters directly in the same environment. You’ll need to place their cages side by side and introduce them slowly so they have a chance to smell each other and interact across the rails at a safe distance.

After a few days or weeks, if you find them compatible, you can place them in a brand-new, unscented cage. This will give them the opportunity to get to know each other in a neutral environment without feeling overwhelmed by each other.

If you have more than one hamster in one cage, it’s important that you have enough space for them to have their own space. If the cage is cramped, hamsters will fight. You should also make sure each hamster has its own home, water bottle, food bowl, and toys to prevent fighting with each other.

Also, just like children, hamsters can get bored, so changing the cage layout or introducing different accessories often keeps them excited and less likely to walk away.

Clean your hamster’s cage regularly

Although hamsters are relatively clean pets, when two or more are in the same cage, the cleaning work of the hamster cage needs to be done more. Too strong a smell can be stressful for hamsters, so make sure to spot-clean them daily.
