If you are wondering how to keep rabbits cool in summer, the short answer is: keep them somewhere below 25C (77F), out of direct sun, with plenty of water, cool surfaces to lie on, and good airflow. Rabbits cannot sweat, and they cannot pant effectively either, so once the heat builds up in their little bodies they have very few ways to release it. That makes hot weather far more dangerous for a bunny than most people realise.
Hello, Tammy here. Alongside my pottery work I spend a lot of time talking with rabbit owners, and every summer the same worried questions come up. So this is my gentle, practical guide to helping your bunny through the warm months.
What temperature is too hot for rabbits?
Rabbits are happiest between about 12C and 23C (55F to 72F). Once the temperature passes 25C (77F), they start to struggle, and anything above 29C (85F) can bring on heatstroke quickly, especially in humid weather. Long-haired breeds like Angoras and Lionheads, overweight rabbits, and very young or elderly bunnies are at even higher risk.
Do rabbits sweat?
No, rabbits do not sweat. They have a small number of sweat glands, but far too few to cool the body. Instead, they release heat through their large ears, which are full of blood vessels close to the skin. This is why a rabbit's ears feel warm on a hot day, and why gently dampening the ears with cool water is one of the most effective ways to help a hot bunny.
How can I cool down a rabbit in hot weather?
Here are the things that make the biggest difference:
- Move them somewhere cool. A shaded room, a hallway with tiled floors, or even a basement is ideal. Heat rises, so lower floors stay cooler.
- Offer a cool surface to stretch out on. A ceramic or slate tile kept in the shade stays wonderfully cool for hours. As a potter I can vouch for this: fired ceramic holds its coolness beautifully, which is exactly why bunnies love flopping onto it.
- Freeze a bottle of water. Wrap it in a tea towel and place it in their space so they can lie beside it when they choose.
- Keep the air moving. A fan in the room helps, but never point it directly at your rabbit. Draping a damp towel near the fan cools the air further.
- Refresh water often. Offer fresh, cool water in both a bottle and a bowl, and add extra leafy greens rinsed in cold water for hydration.
- Groom out loose fur. Brushing away the moulting undercoat helps heat escape, especially for long-haired rabbits.
What are the signs of heatstroke in rabbits?
Please watch for fast, shallow breathing, drooling, lethargy or weakness, confusion or wobbliness, very red or very pale gums and ears, and in severe cases seizures. Heatstroke in rabbits is an emergency. If you see these signs, move your bunny somewhere cool, dampen the ears and fur with cool (never icy) water, and call your vet straight away. Do not submerge a rabbit in cold water, as the shock can be fatal.
I will be honest about why I care so much about this topic. Many of the families I make hand-painted memorial pieces for lost their rabbits suddenly, and summer heat is one of those quiet dangers that takes people by surprise. My hope is that a few simple habits, a cool tile here, a frozen bottle there, mean your bunny stays safe and hoppy for many more summers. If you share your home with a cat as well, I wrote a similar guide on keeping cats cool in a heatwave.
Frequently asked questions
Can I put ice cubes in my rabbit's water?
A cube or two to keep the water pleasantly cool is fine. Just avoid making the water ice-cold, as very cold water can upset a rabbit's sensitive tummy.
Should I shave my rabbit in summer?
No, please do not shave your bunny. Their coat actually insulates against heat as well as cold, and shaving risks nicking their delicate skin. Regular brushing to remove loose fur is much safer.
Can rabbits stay outside in summer?
Only with deep shade all day, constant fresh water, and daily checks. On days above 25C (77F), it is kinder to bring them into a cool room indoors. Remember that a hutch in the sun heats up like an oven, even with a roof.
How do I know if my rabbit is too hot rather than just resting?
A comfortable rabbit stretches out loosely and breathes slowly. A hot rabbit breathes rapidly, holds its head up or back to get air, and its ears feel noticeably warm. When in doubt, cool the room and check on them often.
Rabbits give us so much gentleness, and they rely on us completely when the temperature climbs. A little preparation truly is everything.
