# Gerbil Care in the UK

UK gerbils should live in **same-sex pairs or small groups** in a spacious tank with deep bedding for digging. According to the RSPCA, **wet tail** (diarrhoea with soiled hindquarters) is an emergency — seek vet care the same day.

## Housing

According to the RSPCA, gerbils are desert-adapted burrowers who need space to dig and explore:

- **Enclosure** — glass tank with secure mesh lid or gerbil-safe cage; deep **bedding** (paper-based or aspen — avoid pine and cedar shavings)
- **Digging depth** — at least 20–30 cm of substrate where possible; digging is essential behaviour
- **Nesting** — hay and shredded paper in a house or box for sleeping
- **Wheel** — solid surface, large enough that the back stays straight; open rung wheels cause injury
- **Location** — quiet room, stable temperature, away from direct sun and draughts
- **Cleaning** — partial cleans preserving some nest material; full strip-outs stress gerbils and disrupt scent groups

Gerbils gnaw constantly — provide **untreated wood chews** and cardboard for dental wear.

## Pairs and groups

According to RSPCA guidance, gerbils are **highly social** and should not live alone unless a bereaved gerbil cannot be re-paired after careful introduction attempts.

| Approach | RSPCA recommendation |
|----------|---------------------|
| Best option | Same-sex **littermate pair** from the same litter |
| Groups | Small same-sex groups possible if raised together |
| Introductions | Adult introductions often fail — split immediately if fighting |
| Mixed species | Never with hamsters, mice or other rodents |

Signs of group harmony: sleeping together, grooming each other, shared burrows. Signs of conflict: chasing, biting, vocal squeaking, one gerbil excluded from food or sleep areas — separate into duplicate setups if needed.

## Diet

According to the RSPCA and PDSA:

- **Base diet** — complete gerbil mix or pellet formulated for gerbils
- **Fresh food** — small amounts of carrot, broccoli, apple (no seeds) or herbs — introduce gradually
- **Protein** — occasional mealworm or plain scrambled egg as treat; not excessive
- **Water** — bottle checked daily for blockages; fresh water always

Avoid sudden diet changes — they trigger digestive upset. Remove uneaten fresh food within a few hours.

## Handling and enrichment

Gerbils are generally friendly but fast — handle low over a safe surface or in a playpen. Scoop from below rather than grabbing from above.

Enrichment ideas from RSPCA welfare guidance:

- Cardboard tubes and boxes
- Sand bath with chinchilla sand ( shallow dish, not dust bath powder)
- Scatter feeding to encourage foraging
- Tunnels and platforms

## Wet tail and other health concerns

### Wet tail

Despite the name (more associated with hamsters), **wet tail** in gerbils means **diarrhoea with wet, soiled fur** around the tail and hind legs. According to the PDSA, causes include:

- Bacterial infection (e.g. Lawsonia, Campylobacter)
- Stress from overcrowding, recent transport or bereavement
- Diet change or contaminated food

**This is an emergency.** Gerbils dehydrate and decline within hours. Contact your vet immediately — do not wait or rely on shop-bought remedies alone.

### Other warning signs

Same-day vet attention if you notice:

- Not eating or drinking
- Lethargy or hunched posture
- Laboured breathing or nasal discharge
- Overgrown teeth or weight loss
- Seizures or head tilt

Register with a **small-animal vet** before problems arise — gerbils hide illness until advanced.

## Buying gerbils responsibly

According to the RSPCA, buy from a reputable breeder or rescue — not pet shops sourcing unknown backgrounds without health history. Ask about age, sex, group compatibility and recent health.

Minimum age at homing is typically **6–8 weeks**, already bonded in pairs.

## FAQs

### Should gerbils live alone or in pairs?

Gerbils are social and should live in same-sex pairs or small groups from a young age — ideally littermates. Introducing adults is difficult and often results in fighting. Never house gerbils with hamsters or other species.

### What is wet tail in gerbils?

Wet tail describes diarrhoea with matted fur around the tail and hindquarters. It indicates serious illness — often bacterial infection or stress-related gut disease. It is an emergency; contact your vet immediately.

### What should I feed my gerbil?

A balanced gerbil mix or pellet plus small amounts of safe fresh vegetables. Provide constant access to fresh water. Avoid sudden diet changes and high-fat or sugary treats.

### How big should a gerbil cage be?

The RSPCA recommends as large a tank or enclosure as you can provide, with deep bedding for digging — gerbils are active burrowers. Multi-level space and a solid-based wheel help meet exercise needs.
