Before getting a hamster, it’s crucial to understand these key points covering environment, diet, health management, and more:

1. Housing Setup
Cage Selection
For dwarf hamsters, the cage floor area should be at least 4,500 cm²; for Syrian (teddy bear) hamsters, it needs to be 6,000 cm² or larger, with a height of no less than 30 cm.
Wire cages should have grid spacing of ≤1 cm to prevent escapes. Acrylic cages require enhanced ventilation to avoid stuffiness.
Essential Accessories
A running wheel with a diameter of ≥20 cm (28 cm for Syrians).
Ceramic or wooden hideouts for security.
A dedicated sand bath container.
2. Scientific Feeding Guidelines
Main Food & Water
Choose specialized hamster food with 12%-20% protein. Limit high-fat treats like sunflower seeds to twice a week.
Provide only boiled or purified water, changed daily.
Treat Restrictions
Fresh fruits/veggies (e.g., carrots, apples) should not exceed 1 teaspoon daily.
Never feed toxic foods like onions, chocolate, or garlic.
3. Health & Hygiene Management
Daily Care
Hamsters clean themselves using sand baths—never bathe them with water, as this can cause colds or extreme stress.
Remove feces daily and fully replace bedding once a week. Disinfect the cage with a 1:10 vinegar-water solution.
Disease Prevention
Watch for abnormal behaviors (e.g., excessive scratching, loose stools). Isolate the hamster and consult a vet promptly if issues arise.
4. Interaction & Behavioral Awareness
Adjustment Period
New hamsters need 3–7 days of quiet to settle in. Build trust gradually by hand-feeding treats afterward.
Avoid forced handling to prevent bites or stress.
Nocturnal Needs
Provide night-time activity tools (e.g., running wheels) and minimize disturbances during the day, as hamsters are most active at night.
5. Buying Tips
Prioritize hamsters with smooth fur, bright eyes, and energetic behavior. Avoid those from pet stores with dirty, overcrowded environments.
With proper care, hamsters can live 2–3 years. They require long-term patience and attention from their owners.
