Skin disease in hamsters is a common problem that can cause itching, fur loss and discomfort. While some cases are mild, others may spread or lead to serious infections if untreated. Early detection and treatment are key to keeping your hamster healthy.
  • Hamster skin disease can be caused by parasites, fungus, bacteria or allergies.
  • Common signs include fur loss, scratching and redness
  • Some skin diseases, like ringworm can spread to humans
  • Quick treatment prevents worsening infections and long-term damage

Why Does My Hamster Get Skin Disease?

Hamster skin disease can be triggered by many factors. Parasites like mites or lice irritate the skin, while fungi such as ringworm spread easily in close contact. Cuts or wounds can become infected with bacteria, leading to abscesses. Allergies to bedding, dust or food may also cause irritation. Poor nutrition and lack of vitamins weaken the coat and skin, making problems more likely. In older hamsters, tumors or age-related conditions may show up as lumps on the skin.

Types of Hamster Skin Disease

Parasitic Skin Problems (Mites and Lice)

These tiny parasites burrow into or bite the skin, causing intense itching, fur loss and scabs. Severe infestations make the hamster restless and uncomfortable. If left untreated, scratching can lead to open wounds and secondary infections.

Fungal Infections (Ringworm)

A contagious skin disease caused by fungus, not worms. It appears as circular bald patches with red, inflamed edges. Ringworm spreads quickly to other hamsters and even to humans, making it a serious health concern that requires prompt treatment.

Bacterial Infections

Small cuts or scratches can easily get infected. The skin swells, produces pus and often has a foul odor. In severe cases, abscesses form under the skin, which may need draining or antibiotics.

Allergic Reactions

Dusty bedding, perfumed cleaning sprays or certain foods may cause allergic reactions. Allergies usually show as mild redness, persistent scratching and gradual thinning of fur.

Nutritional Skin Issues

Diets lacking vitamins and minerals can weaken a hamster coat. Poor nutrition leads to dry, flaky skin, brittle fur and slow wound healing.

Tumors or Growths

Older hamsters may develop lumps or growths under or on the skin. These can be harmless fatty lumps or cancerous tumors that require a vet’s assessment.

Symptoms of Hamster Skin Disease

Excessive Scratching and Biting

Continuous scratching or biting at the skin, sometimes until blood or sores appear.

Redness and Irritation

Inflamed skin that looks sore, sometimes warm to the touch. In fungal cases, redness forms a ring around bald patches.

Dry, Flaky Skin

White flakes, like dandruff, appear on the coat. Often linked to fungal infections or poor diet.

Bad Odor

Bacterial infections give off a strong, unpleasant smell that lingers on the skin or bedding.

Bald Patches and Fur Loss

Round or irregular bald spots are common with mites, ringworm or allergies. Fur loss may spread quickly if untreated.

Scabs, Crusts, or Sores

Damaged areas from scratching or infection may crust over or ooze fluid. These spots are painful and attract bacteria.

Swelling or Lumps

Infections, abscesses, or tumors can appear as raised areas. Some swellings are soft, others firm.
