Mr Snoop turning off his fan.
Today is the hottest May day on record. Yesterday, the temperature here reached around 32°C, and last night, records were broken, with temperatures remaining in the high teens. It’s currently 33°C here in southeast England, and is forecast to be a ‘tropical night’, with temperatures staying above 20°C.
As temperatures surge, it’s hard to know what to do to help the bunnies. Heat health alerts are in place for humans, but rabbits cope even more poorly with heat than we do. Anything above 25°C is too hot for them, as they struggle to regulate their body temperature. In the wild, rabbits can retreat to their underground burrows to avoid the heat (they also tend to be active only during the cooler twilight hours), but our domestic rabbits don’t have that option, and, to make matters worse, many breeds have thicker fur than their wild cousins; also, they don’t have the option to move as far to find a place to keep cool.
In high temperatures, rabbits can suffer from heatstroke, and the heat also increases the risk of gut stasis, due to dehydration, and the risk of flystrike.
The current exceptional heat was very sudden, demonstrating that we need plans in place for making them comfortable and keeping them healthy. This late-May heatwave might be exceptional, but the temperature records are being rewritten every year now.
So, what can we do? Bringing them into an air-conditioned room is ideal, but not all of us have that option, so here are some suggestions.
Monitor
Probably the most obvious but also the most vital measure is to keep an eye on the weather, so that we can take steps in time, and to monitor our rabbits’ behaviour and health, so we can respond accordingly.
Provide shade and ensure airflow
Check that rabbits have large areas of shade throughout the day (shadows move!). The air needs to be moving to keep them cool. A gazebo could be placed over the enclosure, or a damp towel draped over (but not enclosing them) can give an evaporative cooling effect. If temperatures are high, it’s often safest to bring outdoor rabbits inside to a cool, quiet room. Sheds might seem shady, but they can become dangerously hot without appropriate measures to keep them cool. For indoor rabbits, close curtains/blinds, and move them to a cooler room if necessary. Most rabbits are sensible about moving to shade if temperatures soar, but elderly and other less mobile rabbits might find it harder to move out of direct sunlight, so they should be restricted to shady areas during daytime.

Standing an iced bottle of water in front of an electric fan can create a cool breeze, but ensure any cables are out of reach (USB rechargeable fans are best), and that rabbits can move away from the airflow if they wish. For indoor rabbits, close the windows, especially on the sunny side, during the hottest hours, and open in the evening and first thing in the morning, before temperatures rise.
Keep rabbits hydrated
Ensure water is refreshed regularly, and easily accessible, especially for less mobile rabbits. Provide a few extra bowls near their favourite resting places, to remind them to drink. It’s helpful to offer leaves which have been soaked in cold water.

Provide cool items
All our rabbits have enjoyed resting against cooler items during hot weather. We use an ice pack and frozen water bottles – generally, the advice is to wrap these in old towels, so they’re not too cold, but Mr Snoop likes to chew fabric, so, for our bunnies, it’s safer not to. Ceramic tiles can also provide patch for cooling down.
Yesterday, we bought a couple of SnuggleSafe Cool Pods – our bunnies often refuse to use anything we think is a good idea worth the price, but they took to them straightaway. The pads don’t need to be frozen – instead, they cool as the rabbit sits on/against them. As with the ice pack and water bottles, check for any signs of chewing.
Keep their trays and enclosure clean
Flystrike is more common during hot weather, especially if rabbits are sitting in a dirty area, so it’s even more important to keep their trays and environment clean.
Keep on top of brushing
Rabbits shed fur as the weather warms up, but it takes time – they can’t just switch to their summer clothes. Regular brushing helps remove excess fur, and reduces the amount ingested during grooming themselves/their companions, which could lead to gut stasis when combined with dehydration during hot weather. Long-haired rabbits should be trimmed.

Dampen their ears
Rabbits can’t lose heat by sweating or panting, like other animals. They regulate their body temperature primarily through their ears, via the network of blood vessels. So, if they’re hot, some rabbits like to have their ears dampened with a cool wet cloth or mist spray, which creates an evaporative cooling effect.
Recognise heatstroke and act immediately
Knowing our rabbits well enough to spot signs of illness is essential, as they’ve retained their prey creature instinct to hide symptoms. Heatstroke develops quickly, so it’s important to be able to spot it. A rabbit suffering from heatstroke may be weak, lethargic, and panting. Their ears will be hot, there may be wetness around their nose, and as the heatstroke progresses, they may be confused and even suffer convulsions. It’s an extremely serious condition, which can be fatal, so requires immediate veterinary attention. Rabbits should be cooled down by dampening their ears with cool water, but they should never be submerged in cold water.
Here, the bunnies have been sensible today – they enjoyed some time on the patio first thing this morning, before the sun reached it. Then we closed the patio door and the curtains, and they’ve spent the day resting beneath the table, next to the various cold items, enjoying the occasional extra bunch of wet coriander. Stay cool everybun!
