Sometimes, a Hamster bite can cause severe bleeding, which should be immediately stopped by applying pressure.

If the cut is in a sensitive area or near to any significant artery, then make a visit to the doctor, or else it can lead to severe damage. In some cases, the bite can even lead to some skin conditions.

  • Rabies: Rabies is another rare diseases among Hamsters. It can be transferred to humans once Hamsters are infected with it.
  • Tetanus: That is a common bacterial toxin that can enter our body through the wound. We should take a tetanus shot as a precautionary measure.
  • Few other diseases like skin infections can affect us. But this is not transferred by biting. Instead, they are passed on by skin contact.

Hamster bites resulting in any disease are rare phenomenon, and you can always visit a doctor if you have any suspicions.

As the teeth of our Hamsters are not sterilized, their bites can be a potential source of bacteria. If these bites are left untreated, it can be infectious.

How To Cure A Hamster A Bite?

Most Hamster owners are bit by their little ones, one day or the other. Although Hamsters are docile creatures, sometimes they can be aggressive or impatient and bite their owners.

Being prey animals, Hamsters can easily feel stressed and terrified for petty reasons.

In all situations, you must be prepared to help yourself when a Hamster bites you. Follow the steps listed below, it will help you with the treatment and get instant relief.

Access The Severity Of The Wound

Firstly, it is important to assess the severity of the wound before taking any further steps.

Not all Hamster bites are the same. Sometimes the wound may be quite deeper than usual. It depends mostly upon the shape and size of the teeth of your Hamster.

Usually, Hamster bites can be treated at home but in a few rare cases, professional advice is important.

Once your Hamster bites you, stay away from them for a while as they may bite you again. 

It is advised to place a clean wet cloth on the wound and apply a little pressure to stop blood loss. After the blood flow stops, you must inspect the wound.

You may require stitches in certain cases, some of them are:

  • If the would is deeper than 1 centimeter or 0.3 inches
  • If the would is near any sensitive area, such as your face or neck
  • The blood flow is not stopping even after placing the cloth and applying pressure for ten minutes

If you have any of the above issues with the wound, then it is suggested to visit a doctor for treatment.

Clean The Wound With Cold Water

After you are done applying pressure on the wound with a clean cloth for ten months, then inspect the wound. Did the flow of blood stop? In some cases, blood may still drip. You should stop using force at this point in time.

Wash the would properly with clean and fresh water after the blood flow has stopped. This is important because the teeth of Hamsters are not always clean and contain food particles and germs.

Also, cleaning the would will help you remove any debris and bacteria.

You can wash the wound with tap water or any bottled water, whatever available at that moment. Just clean the wound with water and do not rub or massage the wound as it can start to bleed again.

You should use some antibacterial soap to wash the wound. This is a suggested measure to eliminate all the dirt particles. It may pain when you’re using soap, but it is important.

 If in any way the dirt enters the blood through the cut, then it can be infectious. 

Apply Some Antibiotics Over The Wound

After you are done washing the wound, use a clean and dry cloth to cover the cloth. Do not rub the would while you place the cloth. If you rupture it, it can cause further problems.

Dry the wound completely, as the leftover water particles will develop into pus and won’t let the wound repair fast.

After that, apply some antibiotic ointment such as Neosporin. This will help to reduce bacterial activity and hence prevent any infection.

Even if a bacterium exists inside the wound, the ointment would not allow it to grow and therefore help to heal the wound more rapidly. 

It also moisturizes the wound, which eliminates any inflammation. You should still take some pain-relieving ointments, if it is sore.

Dress The Wound (To Keep Infections Away)

In most cases, Hamster doesn’t bite hard and the wound is not always deep, you can leave the scare open to heal.

As the bleeding stops, apply some ointment and put on a bandage. This will help to keep the skin around the wound moist.

Moist skin helps the skin recover faster in the following ways:

  • The formation of tissue is faster.
  • Safeguarding against any infection.
  • Reduce the formation of scars.

It is crucial to cover the wound with a suitable bandage that will protect the wound from any further physical injury. Even if there is some bleeding, the dressing will absorb the blood.

You must cover the wound completely as it is better to cover a larger area than the injury. Affix the dressing with an adhesive bandage, like Band-Aid or any surgical tape.

Check For Signs Of Infection

You must monitor and keep a check on the wound on a regular basis. Do not leave the dressing unchanged for more than a day and check out for infections.

If there is bleeding, the bandage can adhere to the skin. In such situations, do not pull the bandage, instead, soak the dressing in water to ease up and then strip the bandage slowly. 

Once the bandage has been removed, wash the wound with water. Dry the wound with a towel, and check the wound.

Test to see how the wound heals day by day. If the injury does not improve, there is a risk of infection. Check for the following signs: 

  • The skin surrounding the wound is red or colder than the temperature of the body
  • Inflammation
  • Some bad scent comes out of the injury
  • Ache over a longer time than a day 
  • Production of pus (On the first day, a transparent discharge of dead cells will be produced, but an opaque, thick discharge after that is not correct)
  • Lack of sensation near the wound. 

Symptoms will be serious, such as fever, nausea, fatigue, and pain when the infection progresses. 

All of the above signs is an indication of illness or any disease that can be spread from Hamsters, and you should visit your doctor immediately.

Do I Need A Tetanus Shot After A Hamster Bite?

In most cases, home treatment is sufficient for Hamster bites. Still, many owners prefer to take a tetanus shot or tetanus booster after being bitten by a Hamster.

Tetanus is caused by bacteria entering the body from the wound. The chance is greater when we get hurt in the open space since the bacteria are embedded in the soil. Animal bites can lead to tetanus, too.

The rate of infection from tetanus is significantly low; still, you must take the precautionary measure.

If you haven’t received the tetanus shot in the past five years, it is best to take it. Know that the vaccine should be given within 48 hours of the incident.

Rabies is another illness that you should be careful with. It’s intermittent among Hamsters. There is also a vaccine available for this purpose. 

Rabies virus spreads by saliva. So there’s a risk that it could spread from an animal bite. If you suspect that your Hamster has rabies, visit the veterinarian promptly. The illness must be treated at an early stage, or it could be fatal.
