# 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.
