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

UK pet rats need **compatible company** (same-sex pairs or groups), a large enriched cage kept at 19–23°C, rat-specific pellets, and daily interaction at dawn and dusk. According to the RSPCA, rats hide pain — contact your vet the same day if eating or behaviour changes.

## Companionship

According to the RSPCA, rats are highly social and should **never be kept alone**. Keep same-sex pairs or trios bonded from youth. Introduce new rats carefully on neutral territory — never add a lone rat to an established group without slow introduction.

## Housing

- **Cage** — large, escape-proof, with multiple levels for climbing
- **Temperature** — 19–23°C; out of direct sunlight (bright light stresses albino strains)
- **Bedding** — wood chips (non-aspen), cellulose chips or shredded paper; avoid dusty sawdust
- **Enrichment** — hammocks, tunnels, ropes, foraging toys rotated regularly
- **Location** — away from loud appliances — rats hear ultrasound from vacuums and speakers

Provide multiple hideouts so each rat can retreat. Keep toilet areas separate from sleeping and feeding zones.

## Diet

| Food | Role |
|------|------|
| Rat pellets | Complete daily base diet |
| Fresh veg and fruit | Small portion of daily allowance |
| Cooked egg, grains | Occasional enrichment |
| Treats | High-fat/sugar foods sparingly only |

Feed twice daily (morning and evening) and remove uneaten fresh food. Multiple water bottles prevent competition.

## Handling and enrichment

Rats are intelligent and trainable with positive reinforcement. Allow free-roam time in a rat-proof room once handled confidently. Never force interaction — return frightened rats to their cage.

## Common health problems

| Problem | Signs |
|---------|--------|
| Respiratory disease (Mycoplasma) | Sneezing, porphyrin staining around nose/eyes |
| Tumours | Lumps, weight loss — common in older rats |
| Head tilt | Circling, rolling — urgent neurological care |
| Overgrown teeth | Weight loss, drooling |

## Preventive care

Annual vet checks, weight monitoring, and prompt neutering of mixed groups. According to the RSPCA, regular handling helps you spot subtle behaviour changes early.

## When to call the vet

Book same-day care for reduced eating, laboured breathing, head tilt, bleeding, or sudden lethargy. Rats can mask illness until they are critically unwell.

## FAQs

### Do rats need company?

Yes. The RSPCA recommends keeping rats in compatible same-sex pairs or small groups. Solitary rats often show stress-related illness.

### What should I feed pet rats?

Commercial rat pellets plus small amounts of fresh vegetables, fruit and cooked egg. Avoid rabbit or guinea pig food — rats are omnivores with different nutritional needs.

### When is a rat health problem an emergency?

Same day if not eating, breathing fast, head tilt, bleeding, or sudden lethargy. Rats hide pain as prey animals and can deteriorate within hours.
