How to Get a Hamster out of Hibernation

Last Updated: February 21, 2022 References Approved

Many animals have developed the ability to hibernate as a natural way to increase chances of survival during the long, cold winter season. Hamsters typically go into hibernation mode in the wild during the wintertime when the temperature drops below 40°F (4.5°C). Being mindful of their temperature sensitivities is an important part of being a hamster owner.

Determining if Your Hamster is Hibernating

1
Know the signs. Sometimes it can be hard to tell if your hamster is simply hibernating or if it has actually died. Hamsters in a hibernating state appear still and lifeless; their breathing and heart rate slow down. They even might go weeks without eating. And with such tiny bodies, it can often be difficult to notice the subtle signs of life in a hibernating hamster.^{[1]

Watch for movement. During true hibernation, hamsters will move very little. But sometimes they can enter a “sleep” phase of minor hibernation in which they often tremble or nod their head from side to side.^{[2]

Check for signs of breathing. During hibernation, your hamster’s breathing will be slower than usual, but not altogether absent. Hold your hamster in your hand and listen closely for breathing sounds. You can also put your finger near their mouth to see if you can detect any exhale breaths.
4
Feel for body warmth. A hibernating hamster will maintain a warm body temperature though it might be slightly cooler than usual. A hamster that is truly dead will lose its body heat completely, so a warm hamster is probably a hibernating hamster.^{[3]

Bringing Your Hamster Out of Hibernation

1
Try body heat. Pick your hamster up and hold it in your hand against your body. Use your body heat to provide warmth for your hamster. Keep holding it for at least 30 minutes and see if there are any changes in their behavior or if they start acting more alert.
2
Warm your hamster with a hot water bottle. Wrap your hamster in a towel with a water bottle full of hot water. Make sure the hamster is not directly touching the water bottle and doesn’t get too hot. This will help warm his body and bring him out of hibernation.^{[4]

3
Use a heating pad. Try placing your hamster on a warm heating pad that is heated to about 90°F (32°C) for 30-60 minutes. This will help your pet warm up quickly and help them come out of their state of hibernation.^{[5]

- If you don’t have a heating pad, try putting your hamster on a towel on top of a radiator. This will have the same effect. Just make sure you monitor your pet closely and make sure the heat isn’t too much for it to handle.
4
Give your hamster warm milk. Once your hamster starts becoming more alert, even if only slightly alert, try to give it warm milk through a medicine dropper. You should heat the milk up in the microwave or on the stove but test it first to make sure it is not too hot. It should be tolerable to the touch. Feed it to your hamster in a bowl or in their water dropper container.^{[6]

- Alternatively, you can try to give your hamster plain water, water with sugar, or children’s Pedialyte with a medicine dropper.^{[7]

Preventing Future Hibernation

1
Make sure your hamster always has enough food and water. Sometimes hibernation is triggered by a lack of food or water in order to conserve energy. To avoid sending your hamster into hibernation, ensure that it always has access to plenty of food and water.^{[8]

2
Provide plenty of warm bedding. The bedding in your hamster’s cage will help insulate it and protect it from the cold. Make sure your hamster has sufficient bedding to stave off hibernation. If your hamster starts hibernating, try adding more bedding to prevent this from happening again.^{[9]

3
Give your hamster a more fattening diet. Having more body fat will help prevent your hamster from going into hibernation mode. Try feeding your hamster more fattening food items like sunflower seeds, peanuts, or avocado. However, be sparing with the fatty foods because a little goes a long way with tiny hamsters.^{[10]

4
Be proactive during the winter. During the cold winter months, be more mindful of your hamster’s behavior and if it seems warm enough. Maybe give your hamster some extra bedding in its cage during the winter and provide more fatty foods than normal. Keep an eye on your pet to make sure it stays safe and alert during the cold season.

Once placed in a warm environment, most hamsters wake up after a couple of hours. Be sure to put the hamster in an escape-proof container, in case they wake when you are out of the room.

Hibernation in hamsters is triggered by temperature rather than season. Thus, if it's winter outside but the heating is on in the house, a hamster is unlikely to hibernate. But if there's no heating and the house is chilly, a pet hamster could hibernate.
