Why do Gerbils get sudden large lumps?

Sudden large lumps in gerbils can be concerning and may indicate various health issues. Here are some possible causes:

Abscesses: These are localized infections that can cause swelling. They are often painful and may require veterinary treatment to drain and treat the infection.

Tumors: Both benign and malignant tumors can appear as lumps. Tumors in gerbils can develop in various organs or tissues.

Cysts: Fluid-filled sacs can form under the skin or in internal organs. Cysts can vary in size and might need to be evaluated by a vet.

Injuries: Trauma or injuries can cause swelling or lumps. If the lump appears after an incident, it might be related to a recent injury.

Abscesses: These are pockets of pus that form due to infection and can cause swelling.

If you notice a sudden lump on your gerbil, it's best to consult with a veterinarian who specializes in small animals. They can provide an accurate diagnosis and recommend appropriate treatment.
