# Hamster (*Mesocricetus auratus*)

> The Syrian or golden hamster is the most popular pet hamster, a small nocturnal rodent that stores food in cheek pouches and must live alone as an adult. With good care, hamsters live 2–3 years and need a large enclosure, deep bedding for burrowing, and a species-appropriate wheel.

- **Category:** Mammal
- **Conservation status (IUCN):** Domesticated
- **Range:** The Syrian hamster's wild range is a small area of steppe in Syria and Turkey; pet hamsters are captive-bred worldwide.

## Cheek pouches and hoarding

Hamsters have expandable cheek pouches that stretch to their shoulders, allowing them to carry food back to hidden stores. In the wild this behaviour supports survival in arid steppe where food may be scattered. Pet hamsters still hoard even with a full food bowl.

## Nocturnal burrowers

Hamsters are active mainly at night and need deep bedding — 20 cm or more — to dig burrows and feel secure. A too-small cage or wheel causes stress, obesity, and spinal injury. Syrian hamsters are strictly solitary; keeping adults together usually leads to fighting.

## Wild origins and domestication

Syrian hamsters were first collected from near Aleppo in the 1930s and bred for laboratory use before becoming pets. Wild populations are fragmented and considered vulnerable in their native range, though the domestic pet trade relies on captive breeding.

## Responsible pet care

Choose a enclosure meeting modern minimum size guidelines, provide a solid-surface wheel large enough to prevent back arching, and offer enrichment such as tunnels and chew toys. Hamsters are prey animals that may nip when startled awake; gentle handling builds trust over time.

## Frequently asked questions

### What is the most popular hamster breed?

The Syrian or golden hamster is the most popular pet hamster — larger and easier to handle than dwarf species, and it must live alone.

### Can hamsters live together?

Syrian hamsters must be housed alone. Some dwarf species tolerate pairs or groups if introduced young, but fighting is still common.

### How long do hamsters live?

Most pet hamsters live 2–3 years. Roborovski dwarfs may reach 3.5 years with excellent care.

### Are hamsters good pets for children?

They can suit older children who respect nocturnal schedules and gentle handling. Hamsters sleep by day and may bite if grabbed while asleep.

### What do hamsters eat?

A quality commercial hamster mix plus small amounts of fresh vegetables and occasional mealworms or boiled egg for protein. Avoid sugary treats and foods toxic to rodents such as onion and citrus.
