Hamster care — AEMV guide distilled
The most common pet hamster is the Syrian (golden) hamster (Mesocricetus auratus); others include the Chinese and Siberian (dwarf) hamsters. They are nocturnal, relatively inexpensive to keep, and known for cheek pouches used to carry food to the burrow.
Housing & environment
- Enclosure must be strong metal or glass, escape-proof (hamsters gnaw through wood, plastic and soft metals), with a secure lid and solid-bottom flooring. Offer at least 150 sq in of floor space, height 6–10 in (15–25 cm), plus a nesting/hide box with deep litter.
- Maintain 65–79°F (18–26°C) (young 71–75°F), relative humidity 40–70%; avoid direct sunlight. Use a solid-floor wheel to prevent leg damage. Avoid pine, cedar and corn cob bedding; paper or soft wood shavings are suitable.
Diet & nutrition
Feed a commercial uniform pellet (rodent block) — seed-mix diets let hamsters select only favored parts, causing dietary deficiencies, obesity and even diabetes. Young hamsters begin solid food at 7–10 days of age. Provide drinking water via sipper tubes, changed daily.
Behavior & veterinary care
Most hamsters should be housed individually; some Siberian hamsters may be social but need careful introduction. They may bite when roughly handled, suddenly disturbed, or when ill/in pain. An annual exam is recommended; seek veterinary care promptly for any sign of illness.
Common disorders
AEMV lists behavioral (litter abandonment/cannibalism, inter-adult aggression); cardiac (especially older adults); dental (cheek-pouch impaction/infection, malocclusion, overgrowth); dermatologic (mites, bacterial infection, contact dermatitis); endocrine (Diabetes, hyperadrenocorticism); gastrointestinal (diarrhea "wet tail"); lymphoma; obesity; and trauma.
