What are the common diseases of a pet mouse?

The pet mouse values ​​its cleanliness and that of its environment. The litter box is one of the essential elements to guarantee good hygiene, along with the regular cleaning of the cage. Because the mouse is a fragile animal. Here are the common diseases that a house mouse can catch.

Respiratory diseases

A dusty litter, a cage placed in full drafts, a room exposed to sudden changes in temperature, cleaning of the cage not frequent and regular enough … Respiratory disorders in mice are quite common and can have various causes .

Pasteurellosis and mycoplasmosis are two bacterial diseases infrequent. Bacteria thrive due to a weak immune system or animal fatigue. In the first case, the mouse is feverish and exhibits difficulty in breathing. Treatment consists of prolonged antibiotic therapy. In the second case, the bacteria first lodge in the nose and ear of the animal without causing symptoms. These appear with its progression in the body of the mouse: sneezing then wheezing occurs. Bronchitis or pneumonia can occur. Antibiotics are the most commonly used treatment.

It is more likely that your mouse will simply catch a cold and its cold worsens into a more serious infection. Never delay getting your pet treated!

Skin diseases

The scabies is certainly the most common skin disease in mice. It often develops through a mite that settles on the skin of the animal and results in a significant loss of hair, by itching, especially of the neck, muzzle and ears. The vet will likely prescribe anti-parasite baths and lotions. It will also be necessary to disinfect your entire home.

Ringworm is caused by small fungi. The disease remains rare in mice. Once contaminated, it loses its hair and on its skin, scabs form. Like scabies, it is spread to humans and you will need to clean your home. If you have similar symptoms, avoid touching your mouse or handle it with gloves when taking it for examination.

Eye damage

The same causes that cause respiratory illnesses can cause conjunctivitis. As in humans, the eye swells and tears. Scabs and pus appear soon after. Only the medication prescribed by the veterinarian will cure your mouse.

Breast tumors

Common breast tumors are signaled by growths that you can identify either with the naked eye or by touch. They are usually seen in old mice. Only the operation under general anesthesia can prevent death in mice, but few veterinarians practice it.


It is not a disease in itself but the symptom of excessive consumption of fruits or vegetables, poor hygiene, too cold water, or the presence of a parasite in the intestines. It should not be long before you take him to the veterinarian because the mouse is visibly thinner and it can die pretty quickly.
