Before You Bring Pet Rats Home
A practical checklist for companionship, housing, daily care and finding a vet.
A practical checklist for companionship, housing, daily care and finding a vet.
Before bringing rats home, check six things honestly: companionship, cage space, daily time, regular cleaning, veterinary access and budget.
Rats are social, active and inquisitive. They need other compatible rats, a cage that supports natural movement, and daily opportunities to explore and interact. Individuals differ in how much handling they enjoy, so build trust gradually and let them move away when they want space.
Pet rats commonly live around two to three years. Plan for their care through changes in work, travel and household routine, not only the first few weeks.
Keep compatible rats in a same-sex pair or small group. Do not keep a rat alone unless a vet or suitably qualified professional advises it for that individual.
Ask a rescue or responsible breeder about each rat's sex, age, health and social history. If the group changes later, do not rush an introduction. Seek current guidance and watch how every rat responds.
Choose a large, secure and well-ventilated cage with a solid floor. Blue Cross recommends at least 90 × 60 × 120 cm of living space for two to five rats; larger groups need more. The cage should let rats stand upright, climb, stretch, explore and rest at different heights.
Make sure gaps are too small for the smallest rat to put its head through. Keep the cage indoors, away from direct sun, draughts, smoke, strong smells, dust and disruptive noise. RSPCA describes 19–23°C as an ideal temperature range and advises avoiding humidity extremes.
Provide several shelters, ideally one more than the number of rats, with multiple exits. Add nesting material, feeding and drinking points, climbing opportunities and space to forage. Inspect the whole setup regularly for wear, damage and blocked routes.
Use a complete food made for rats and follow its feeding guide. Small amounts of suitable fruit and vegetables can supplement the main diet within the daily allowance. Keep fresh water available and use current RSPCA food guidance or a vet if you are unsure about an ingredient.
Check food, water and wellbeing every day. Provide supervised exercise outside the cage for at least an hour, adjusted to the rats' confidence and health. Protect them from other animals and remove hazards before free-roam time.
Spot-clean through the week and carry out a fuller clean around weekly, adapting to the cage, bedding and group. Retain a little clean familiar nesting material. Use a pet-safe cleaner as directed, rinse where required and let the cage dry before the rats return.
Before the rats arrive, identify a practice that treats small mammals. Ask whether it sees rats and how normal and out-of-hours care works. RCVS Find a Vet is a useful starting point, but contact the practice directly to confirm current services.
Learn what is normal for each rat. Check for changes in breathing, appetite, weight, activity, posture, eyes or nose, movement, social behaviour and new lumps or injuries. Weigh rats regularly in a consistent way and record changes. Contact a vet promptly if something is new, persistent or worsening.
Sneezing and respiratory noise can have different causes. Do not diagnose them from an online guide. Frequent or persistent sneezing, discharge, wheezing, altered breathing, appetite loss, weight loss, lethargy or a hunched posture needs veterinary advice.
If a rat is struggling to breathe, breathing with its mouth open, gasping, collapsing, severely weak or turning blue or grey, contact an emergency vet immediately.
Price the cage, food, bedding, enrichment, carrier and regular replacements before committing. Ask nearby rat-treating practices for current consultation and out-of-hours prices. Insurance, exclusions and practice fees change, so use current quotes and keep a realistic plan for unexpected veterinary costs.
