Outdoor rabbits need more than a cover over a hutch when winter arrives. Keep their water available, their sleeping area dry and their exercise space usable. This guide turns those jobs into a preparation checklist and a routine you can share with everyone who cares for them.
Updated 24 September 2026: revised the winter water routine, housing advice and signs that require an immediate vet call.
If your rabbit is eating less than usual, contact your vet straight away. A rabbit that stops eating or producing droppings needs urgent veterinary help. Do not wait until the next morning or for a fixed number of hours, and do not assume lethargy is winter sleep: rabbits do not hibernate. See PDSA’s reduced-appetite guidance.
Before the first cold spell: check the whole enclosure
Walk around the sleeping area and exercise area while it is light. Look underneath the roof, around door frames and along the floor for water marks, gaps, rot or sharp edges. Check hinges, bolts, mesh and the route between shelter and run. A cover cannot repair a leaking roof or make an insecure enclosure predator-proof.
- Repair leaks and secure loose covers before bad weather.
- Position the enclosure away from driving rain and strong winds; keep it out of standing water.
- Store spare dry bedding, feeding hay and clean water containers where you can reach them easily.
- Keep a torch and the vet’s usual and out-of-hours numbers ready.
- Decide who checks the rabbits if you work late or are away.
A warm sleeping area still needs an exercise area
A hutch should be a shelter within a larger home, not the rabbit’s entire winter living space. The Rabbit Welfare Association & Fund recommends a permanently accessible enclosure of at least 3m × 2m × 1m high for a pair of average-sized rabbits, indoors or outdoors. This is welfare guidance, not a claim that a particular product meets a legal standard. Larger rabbits may need more space.
Keep the route to a sheltered run open and safe. Rain protection should not turn the enclosure into a sealed box. Provide dry places to rest and hide, and keep compatible bonded rabbits together. A guinea pig is not a substitute for a rabbit companion.
Insulation, ventilation and bedding
External covers and protected insulation can reduce weather exposure, but rabbits must not be able to chew them. Leave ventilation openings clear and check for condensation. Do not wrap the entire enclosure tightly in plastic.
RWAF’s cold-weather guidance recommends soft, dust-extracted straw for insulating bedding, while feeding hay remains available separately. Newspaper can form an absorbent layer underneath; replace any damp material promptly. Both rabbits need room to lie together or apart.
If you use a heat pad designed for rabbits, follow its heating and cover instructions, inspect it for damage and allow the rabbits to move away. Do not improvise with exposed cables or direct heat. Blue Cross’s winter guide also explains covers, soft straw and protected heat pads. None replaces dry housing and regular checks.
Water must stay available all night
Never take away the rabbits’ only water source overnight to stop it freezing. Keep a spare bottle or bowl indoors so that you can replace a frozen one immediately. The spare comes inside; the rabbits’ drinking supply stays with them.
The RSPCA winter checklist says to check water at least twice daily. Increase checks during freezing conditions, including before bed and early in the morning. Test the bottle nozzle: visible liquid in the bottle does not mean the spout works. A sturdy bowl alongside a working bottle provides another option, but both need checking.
Insulating covers only help reduce the problem; they do not remove the need to inspect the water. If your arrangement repeatedly freezes between checks, improve the sheltered location or implement your prepared indoor housing plan. Do not add salt or other substances to drinking water.
Plan where they will live if conditions worsen
There is no single outdoor temperature that guarantees safety for every rabbit. Shelter, damp, wind, coat, body condition and health all matter. PDSA recommends moving rabbits’ housing indoors as temperatures approach freezing; a suitable shed or garage that is not used for cars may be an option, provided it remains safe and gives them room to exercise.
Prepare that space before you need it: remove chemicals and cables, cover slippery flooring, arrange the shelter and exercise space, and check the temperature there. A bare shed is not automatically warmer or safer than an outdoor enclosure. Never house rabbits near vehicle exhaust or in a greenhouse.
Avoid repeatedly moving rabbits between a hot room and cold outdoor housing. RWAF advises a settled environment and warns about temperature extremes. Keep familiar items and the bonded companion with them where appropriate. Ask your vet for an individual plan for rabbits that are frail, thin, poorly coated, unwell or recovering from surgery; do not use an age cutoff as a substitute for that assessment.
Keep the diet steady and monitor each rabbit
Continue unlimited good-quality feeding hay, their usual appropriate greens and measured rabbit pellets. Do not replace hay with extra treats or suddenly change the diet because it feels cold to you. Discard frozen or spoiled fresh food.
Check what each rabbit actually eats rather than assuming an empty shared bowl means both are doing well. Record weight and appetite trends, and ask your vet about any weight loss or whether the diet needs adjusting. A rabbit losing weight needs assessment, not simply a larger pellet portion.
A routine for morning, evening and bad weather
| Check | What to do |
|---|---|
| Each rabbit | Watch both move and eat. Note unusual hiding, a hunched posture, reduced responsiveness or difficulty breathing. |
| Food and droppings | Top up feeding hay and check for changes in appetite or the amount of droppings. Contact the vet immediately about a reduction. |
| Water | Refresh it, test bottle flow and check bowls. Repeat more often in frost; leave a working supply overnight. |
| Bedding and shelter | Remove wet or soiled material. Check leaks, condensation and draughts at rabbit level. |
| After a storm | Inspect covers, locks, mesh and the covered route to the run. Deal with damage before leaving the rabbits unattended. |
Write down anything another carer needs to know. A simple entry such as “both eating hay; water flowing; bedding dry” is more useful than an unexplained tick. Do not let record-keeping delay a call when a rabbit is unwell.
When winter checks become a vet call
Reduced eating, fewer droppings, unusual weakness or a rabbit that seems limp require prompt action. Contact your vet immediately and explain the signs, when they began and the housing conditions. Do not wait two days to see whether appetite improves. Follow the vet’s advice about transport, warmth, food and fluids; do not start medicines or home treatment on your own.
Questions owners ask before winter
Do healthy outdoor rabbits have to spend all winter in a heated room?
Not necessarily. Suitable, stable housing matters more than choosing the warmest room. Use the welfare guidance above to assess the setup, prepare for freezing weather and ask your vet about individual vulnerabilities.
Can two rabbits keep each other warm?
A compatible rabbit companion is important and they may rest together, but company does not make a damp or exposed enclosure safe. They still need shelter, bedding, space, food and water.
Is putting on a hutch cover enough?
No. Check the shelter, run, water arrangements and daily care routine together. A useful autumn job is to walk through the checklist with whoever will look after the rabbits when you are away.
