How to Care for a Hamster: Complete Guide for Beginners
Everything about hamster care. Ideal cage, diet, exercise, hygiene, and behavior. Learn how to keep your rodent happy and healthy.
Small, fluffy, and full of energy — hamsters have earned their place as beloved pets in millions of homes. But don't be fooled by their size: these little rodents have specific needs that, when met, ensure a long and happy life.
Know the Types of Hamsters
There are several hamster species, each with its own characteristics:
| Species | Size | Temperament | Ideal For |
|---|---|---|---|
| Syrian (Golden) | 6-7 inches | Docile, solitary | Beginners |
| Dwarf Russian | 3-4 inches | Active, may be social | Those who want to see interactions |
| Roborovski | 1.5-2 inches | Very fast, shy | Observation |
| Chinese | 4-5 inches | Calm, agile | Experienced keepers |
For beginners: The Syrian hamster is the best choice. It's larger (easier to handle), docile, and bonds with its owner.
Life Expectancy
Hamsters live relatively short lives:
- Syrian: 2-3 years
- Dwarfs: 1.5-2 years
- Roborovski: 3-3.5 years
This can be difficult for children, so prepare them for this reality.
The Ideal Cage
Size: Bigger is Better
The absolute minimum for a Syrian hamster is 24" x 16" of floor space. But ideal is even larger:
- Good: 32" x 20"
- Great: 40" x 20" or 40+ gallon tank
Those colorful tube cages from pet shops are usually too small.
Housing Options
Wire cage:
- Good ventilation
- Hamster can climb the bars
- Escape risk if bar spacing is too wide
Tank/aquarium:
- Prevents escapes
- Keeps bedding inside
- Needs ventilation in the lid
Bin cages (modified storage bins):
- Economical
- Spacious
- Needs modification for ventilation
What the Cage Needs
Deep bedding (6-10 inches): Hamsters are natural burrowers. Deep bedding allows them to create tunnels, an essential behavior for their wellbeing.
Use:
- Treated pine shavings (phenol-free)
- Shredded unprinted paper
- Corn cob or coconut substrate
Avoid:
- Cedar (toxic)
- Fine sawdust (respiratory problems)
- Cotton (choking and strangulation risk)
Exercise wheel: Essential! Hamsters run up to 5 miles per night.
- Syrian: 11-12 inch diameter wheel
- Dwarfs: 8-10 inch wheel
- Solid surface (no bars)
Houses and hideouts: At least 2-3 different hiding spots.
Water bottle: Bottle type with metal spout.
Food dish: Ceramic or stainless steel (won't tip easily).
Diet
Base Diet
Quality hamster food: Choose mixes with a variety of seeds, grains, and pellets. Avoid foods that are only pellets or have lots of artificial colors.
Amount: 1-2 tablespoons per day
Allowed Supplements
Vegetables (small portions, 2-3x per week):
- Broccoli, cauliflower
- Carrots, cucumber
- Spinach, romaine lettuce
- Zucchini
Protein (1-2x per week):
- Hard-boiled egg (small piece)
- Plain cooked chicken
- Mealworms
Fruits (rarely, high sugar):
- Apple without seeds
- Strawberry
- Banana
Forbidden Foods
- Citrus (oranges, lemons)
- Onions and garlic
- Chocolate and sweets
- Almonds
- Processed/salty foods
- Raw beans
- Tomato (leaves are toxic)
Eating Behavior
Hamsters have elastic cheek pouches where they store food to stash in their nest. This is normal! It doesn't mean they're hungry.
Hamsters Are Nocturnal
A crucial point: hamsters sleep during the day and are active at night.
This means:
- Don't put the cage in your bedroom (wheels are noisy!)
- Don't wake the hamster during the day
- Interact in the late afternoon/early evening
- Hamsters woken forcefully may bite
Handling and Taming
The First Weeks
- Days 1-3: Let the hamster adjust. No handling.
- Days 4-7: Speak softly near the cage. Offer treats through the bars.
- Week 2: Place your hand inside the cage without trying to grab.
- Week 3+: Let the hamster climb onto your hand voluntarily.
How to Pick Up Correctly
- Cup both hands under the hamster
- Never grab from above (looks like a predator)
- Keep close to the floor or soft surface
- Never squeeze or hold by the skin
Biting
Hamsters bite when:
- Scared
- Woken during sleep
- Your hands smell like food
- They're sick or in pain
Always wash your hands before handling your hamster.
Cleaning and Hygiene
Daily
- Remove uneaten fresh food
- Check the water bottle
- Remove visible droppings from the "bathroom corner"
Weekly
- Partial bedding change (replace about 1/3)
- Wash food dish and water bottle
- Check hideouts (may accumulate spoiled food)
Monthly
- Full cage cleaning
- Replace all bedding
- Keep some old bedding to maintain the scent
Important: Don't bathe the hamster! They clean themselves. Bathing causes stress and hypothermia.
For fur cleaning, offer chinchilla sand bath in a dish.
Environmental Enrichment
Hamsters are intelligent and need stimulation:
Toys and Activities
- Tubes and tunnels: PVC pipes, paper towel rolls
- Chew toys: Untreated wood, coconut toys
- Burrowing: Deep bedding is the best enrichment
- Foraging: Hide food in the bedding for them to find
- Playpen: Safe area outside the cage
Teeth Grow Continuously
Hamsters have continuously growing teeth. They NEED to chew to wear them down. Provide:
- Wood blocks
- Hard rodent biscuits
- Apple or willow branches
Health Signs
Healthy Hamster
- Bright, open eyes
- Smooth, shiny fur
- Active at night
- Eats and drinks normally
- Curious and alert
Warning Signs — See a Vet
- Ruffled or dull fur
- Tearing or closed eyes
- Nasal discharge
- Noisy breathing
- Diarrhea ("wet tail" is an emergency!)
- Weight loss
- Lethargy during active period
- Overgrown or misaligned teeth
- Lumps or swelling
Wet tail: Serious bacterial infection, especially in young hamsters. Without treatment, can be fatal in 24-48 hours.
Are Hamsters Solitary?
Syrians: Absolutely solitary! From 8 weeks of age, they MUST live alone. Together, they'll fight to the death.
Dwarf Russians: Can live in same-sex pairs or groups IF they're siblings raised together from birth. Still, fights can happen.
When in doubt: Keep alone. Hamsters don't "feel lonely" like humans.
Special Care
Temperature
Hamsters prefer 68-75°F (20-24°C). In low temperatures, they may enter torpor (looks dead, but is forced hibernation). This is dangerous!
Travel
Hamsters travel poorly. If you must travel:
- Use a carrier with bedding
- Bring food and water
- Maintain stable temperature
- Long trips are very stressful
Children
Hamsters are fragile and nocturnal — not ideal pets for young children. If you have kids:
- Always supervise handling
- Teach them to respect the hamster's schedule
- Prepare for the short life expectancy

A Small Great Companion
Hamsters may be small, but they bring immense joy. Watching them dig tunnels, run on their wheel, stuff their cheeks with food, and explore curiously is enchanting.
With the right care — adequate space, balanced diet, enrichment, and respect for their nocturnal rhythm — you'll have a very happy little furry friend.
Set up the cage, fill it with bedding, and let the adventure begin!
