Hamsters Can Catch Colds: Symptoms and Solutions
I. Cold Symptoms
Typical Signs
Sneezing
Runny nose (clear or pus-like discharge)
Wet nose

Red, swollen, or teary eyes
Severe Symptoms
Lethargy
Excessive sleepiness
Loss of appetite
Weight loss
Difficulty breathing
Even fever or convulsions
Differentiating from Allergies
Cold symptoms are often triggered by temperature fluctuations or damp environments. Allergies, however, are usually caused by irritants like bedding or perfume. To tell them apart, remove potential allergens and observe if symptoms improve.
II. Causes of Colds
Environmental Factors
Sudden temperature drops (temperature difference exceeding 5°C)
Damp cage
Poor ventilation
Unsanitary conditions
Physical Factors
Hamsters with low immunity are more prone to colds due to cold temperatures or bacterial infections.
III. Treatment and Prevention
Mild Colds
Warmth: Maintain the environment at 20-25°C, and use (degreased cotton balls) or flannel bedding.
Nutritional Support: Offer vitamin C-rich foods (e.g., apple chunks) to boost immunity.
Severe Symptoms
Seek veterinary care promptly and use pet-specific cold medications (e.g., amoxicillin nasal drops).
Prevention Measures
Keep the cage dry and clean, and replace bedding regularly.
Avoid direct cold drafts; provide extra warmth in winter.
IV. Notes
Self-Healing Potential
Mild symptoms may resolve on their own, but most cases require intervention. Delayed treatment can lead to complications like pneumonia.
Transmission Risk
Hamster colds do not transmit the plague, but they can spread other respiratory illnesses. Pay attention to personal hygiene when caring for sick hamsters.
