Baby rabbits need warmth, with temperatures ideally around 68-72°F (20-22°C); cooler than that, especially below 40°F (4°C) for newborns, requires supplemental heat like a half-covered heating pad or snuggle disc to prevent chilling, as they can't regulate their own body temperature well and can easily get too cold or even freeze if left in damp, windy conditions or without protection.
The 3-3-3 rule for rabbits (and other pets) is a guideline for adjusting to a new home: 3 Days for the rabbit to feel overwhelmed and hide, 3 Weeks to start settling in and showing personality, and 3 Months to feel truly at home and build a strong bond. It helps adopters manage expectations, understand that fear and skittishness are normal, and encourages patience as the bunny decompresses in its new environment, emphasizing providing a safe space and routine.
Although they may look small and fragile, rabbits are surprisingly well-adapted to cold temperatures. With appropriate husbandry, a healthy adult rabbit can be comfortable in temperatures down to 40 degrees Fahrenheit and can tolerate temperatures that are even lower if necessary.
Any temperature lower than –7 degrees centigrade may be dangerous to rabbits but temperatures above that but below freezing may cause them discomfort if the hutch is either damp or the prevailing wind blows into it. It's vital that any outdoor hutch is dry and weatherproof with plenty of hay.
Shivering: If you notice your rabbit shivering or trembling, it's a clear sign they are feeling cold. Shivering is a natural response to cold temperatures as the body tries to generate heat. Huddling: Rabbits will huddle together or curl up into a ball to conserve body heat when they're cold.
Rabbits are great cool/cold weather animals. We have an outside barn, and we bring babies inside out of the weather if it's below 35 degrees (dry) 40 (wet) until eyes are open are their well haired.
The ideal temperature for a rabbit is between 15-20°C, anything below this puts a rabbit at risk of health problems. Fortunately, rabbits have ways to keep themselves warm, but they also need some help from their owner.
Keep the babies in a warm (about 75o - 78o Farenheit), quiet place in a nest similar to the one described above. (Bunny fur is the best lining, but clean cotton wadding will do as a substitute. Just be sure the babies do not get tangled in it.) DO NOT use an electric heating pad.
Is your shed heated? If the answer is no, then your bunnies are suffering right now due to extreme cold. They have to be kept in a temperature between 12°C and 21°C, but they prefer between 15°C and 18°C for their comfort zone.
The best way to keep both indoor and outdoor rabbits warm is to put plenty of extra, dry bedding material in their sleeping and sheltering areas for them to burrow into. For outdoor rabbits, make sure that their hutch is sheltered, out of the direct wind and rain and covered.
Normal behaviours for rabbits in the winter can include curling up into a ball or huddling together to share body heat. Rabbits actually cope with the colder months pretty well, you'll find them shedding their summer coat for a thicker winter coat to keep warm.
Heat lamps are a must when below freezing for our farm. Some other rabbitries use straw and pack it into each cage for the rabbits to burrow but I prefer an actual heat source for our buns. Remember to always securely attach the heat lamp to the outside of the cage or hutch.
Domesticated rabbits have difficulty with temperatures below 50°F (10°C). Rabbits kept outdoors in climates with temperature extremes must be provided with a fairly large shelter that is heated in winter and cooled in summer.
Rabbits need unlimited access to grass and hay, so they shouldn't ever be left without food. However, if it's an emergency and there's no other choice, then they can go up to 12 hours without eating.
Rabbits are prey animals; that is, they are the ones preyed on by the carnivorous animals (raccoons, dogs, wolves, cats). Raccoons have been known to scare a rabbit to death just by crawling over his cage, never making contact. Your rabbit depends on you to keep him safe.
Bonding can take anywhere from 2 weeks to up to 6 months and takes time, patience, and a second cage to get the process started. Rest assured, all rabbits adopted from Rhode Island animal shelters are required by law to be spayed or neutered. Starting the process with both bunnies spayed and neutered is key.
Observe your bunnies as well as the weather in order to gauge how cold is too cold for your rabbits. If temperatures have been gradually declining over several weeks, your rabbits' coats should be sufficient to keep them warm enough in even sub-zero temperatures.
Shivering: If you notice your rabbit shivering or trembling, it's a clear sign they are feeling cold. Shivering is a natural response to cold temperatures as the body tries to generate heat. Huddling: Rabbits will huddle together or curl up into a ball to conserve body heat when they're cold.
A rabbit was considered normothermic if its rectal temperature was between 38.0°C (100.4°F) and 39.9°C (103.8°F). Hypothermia was defined as a rectal temperature ≤37.9°C (≤100.2°F).
This is dangerous for newborn bunnies since they are born blind, deaf, and hairless with thinner-than-paper skin. They become chilled quickly, and exposure can kill them in minutes. There are several safe methods to warm up a baby bunny, enabling its safe return to the nest box with its siblings and mother.
Make sure your rabbits' home is sheltered from strong winds, rain and cold draughts. It will need insulating – with a special cover or blankets or old carpets – with a waterproof cover on top. But do make sure it's well-ventilated.
Suggested methods to warm your bunny:
The cage is fine for sleeping at night - some rabbits find it comforting to have a covering (towel, light blanket) over the top of the cage at night. You'll definitely need a larger space for during the day time.
So, yes rabbits can get a cold at night, but it depends on the climate and temperature. Read on to learn more about keeping your rabbit safe when the temperature drops.
Temperatures over 80º Fahrenheit can be dangerous for a rabbit. In hot weather, please observe the following to protect your bunny from overheating: NEVER leave a rabbit unattended in your vehicle.
