# Hamster Care in the UK — Diet, Housing & Health

UK hamsters need a **spacious indoor cage** with deep bedding, species-appropriate diet, and quiet predictable lighting. Syrians live alone; dwarf hamsters may be grouped with care. According to the RSPCA, hamsters hide pain — contact your vet the same day if eating, droppings or behaviour change.

## Housing

According to the RSPCA, hamsters should be kept **indoors** — outdoor temperatures can trigger dangerous torpor in domestic hamsters who lack sufficient fat reserves.

- **Cage** — solid floor (not wire mesh), deep dust-free bedding for burrowing, secure lid
- **Space** — room for a large axle-free wheel, hiding places and foraging
- **Location** — quiet room, away from direct sun, draughts, and ultrasonic noise from TVs or speakers
- **Lighting** — predictable day/night cycle; hamsters are nocturnal and sensitive to bright light

Provide a nesting box, chew materials for dental wear, and tunnels for enrichment.

## Species and companionship

| Species | Housing |
|---------|---------|
| Syrian | Always solitary |
| Chinese | Always solitary |
| Dwarf (Roborovski, Campbell's, winter white) | May live in stable pairs/trios — monitor for fighting |

According to the RSPCA, even compatible dwarf groups may fall out later. Have a spare cage ready to separate fighting hamsters immediately.

## Diet

- **Pellets or seed mix** — formulated for hamsters, not rabbits or guinea pigs
- **Fresh veg** — small amounts of carrot, apple, coriander — introduce gradually
- **Avoid** — grapes, rhubarb, sugary or fatty treats except as tiny training rewards
- **Water** — bottle with sipper tube; check daily for leaks and blockages

Scatter-feeding encourages natural foraging. Remove mouldy stored food from hoards promptly.

## Handling and welfare

Handle gently in the evening when hamsters are waking. Never wake a sleeping hamster abruptly. An adult should supervise children's handling — hamsters injure easily with rough contact.

According to the RSPCA, signs of stress include changes in behaviour, urination when handled in new places, and reduced appetite.

## Common health problems

| Problem | Signs |
|---------|--------|
| Wet tail | Diarrhoea, soiled rear, lethargy — urgent vet care |
| Respiratory infection | Sneezing, wheezing, discharge |
| Dental overgrowth | Weight loss, selective eating, drooling |
| Skin mites | Itching, hair loss, crusty ears |

## When to call the vet

Same-day appointment if your hamster stops eating, passes fewer or wet droppings, breathes noisily, or shows sudden behaviour change. Small furries decline within hours without treatment.

## FAQs

### Can hamsters live together?

Syrian and Chinese hamsters must live alone — they are territorial. Some dwarf species can live in stable pairs or trios, but fighting is common and they need separate housing if aggression occurs.

### What should I feed my hamster?

A balanced hamster pellet or seed mix plus small amounts of safe vegetables and fruit. Avoid grapes and rhubarb. Fresh water from a bottle checked daily for blockages.

### When should I take my hamster to the vet?

Same day if not eating, droppings become moist, hindquarters are soiled, breathing is laboured, or behaviour changes suddenly. Hamsters hide pain and deteriorate quickly.
