Take your hamster for a checkup soon after getting it. This first visit can help a vet find health problems early and starts a medical record for your pet.

To find a veterinarian for your hamster, ask other pet owners, search directories for exotic animal vets, or check your state veterinary medical society or the Association of Exotic Mammal Veterinarians (AEMV.org). Choose a clinic that has hamster experience and offers emergency care. The American Board of Veterinary Practitioners (ABVP.org) also lists board-certified specialists in exotic companion mammal medicine.

  • Inactivity

  • Loss of appetite or weight

  • Secretions from the eyes, ears, or nose

  • Hunched back

  • Abnormal walk

  • Scruffy hair or hair loss

  • Diarrhea (“wet tail”)

  • Trouble breathing

Spend time with your hamster every day so you learn what is normal for it. Early signs of illness can include weight loss, low energy, messy fur, breathing trouble, changes in urine or feces, and wounds. Check the area around the rear for stains or secretions.

If your hamster looks or acts different, take it to your veterinarian. The vet will examine the mouth, teeth, cheek pouches, eyes, ears, feet, and belly. A fecal sample might be checked for worms or bacteria. A hamster’s normal body temperature is usually 98–101°F (37–38°C).

Even friendly hamsters can become aggressive if they are sick, in pain, scared, or woken suddenly. A sick hamster might be easier to move in a small container than by hand.

Giving Medication

Hamster medicine is often given by mouth using a dropper or syringe. Give only the exact amount prescribed, because hamsters are small and can be overdosed easily.

Some antibiotics are dangerous for hamsters and can seriously harm their digestive system. Never use medicines or antibiotic creams unless your vet specifically tells you to.

Diarrhea and other illnesses can quickly cause dehydration. A vet might need to give fluids or other medications by injection if that happens.

Preventive Care

Good prevention includes a balanced diet, clean water, clean bedding, and a sanitary cage. One of the most important safety steps is preventing escape. Many hamsters are badly hurt after getting out of their cages.

When your hamster is out of the cage, handle it gently and keep it in a safe, secure place. Hamsters can fall from tables or run off quickly. Never assume one will stay still while you clean the cage.

Vaccinations

No vaccines are required or recommended for hamsters.

Dental Care

Hamsters’ front teeth grow continuously throughout life. They need food and safe toys to chew (such as small wooden blocks) that help wear down the teeth naturally. Overgrown teeth can cause drooling, poor appetite, and weight loss. A veterinarian can trim them if needed.

Hamsters usually have fewer dental problems than some other rodents, but regular checks are still a good idea.
