African pygmy hedgehogs need to be kept at a temperature of 75-80 degrees. When the winter months come along, there are some things to consider to make sure your hedgehog stays warm. If a hedgehog gets too chilly, it will attempt hibernation. Pet hedgehogs are not equipped to hibernate, a hibernation attempt can lead to death.
1. The first thing to consider is the cage type. Midwest cages are quite long and may need multiple heat sources. Barred cages are open and don't hold heat well. Monitor temperature with multiple thermometers throughout the cage. You may need to bump up the temperature of the heat source.
I prefer plastic tote cages, they hold heat pretty well.
2. Dont keep the cage on the floor. The floor can be cold and drafty. Try putting the cage on a stand or dresser.
3. Keep your cage against an inner wall and away from the windows. Exterior walls and windows are drafty.
If you notice your hedgehog being lethargic, walking with a wobble and/or has a cold belly, this is likely a hibernation attempt. Warm your hedgehog by placing them on your bare chest or belly.
Do not warm your hedgehog in a bath, the quick temperature change could lead to shock.
Once your hedgehog is warmed up, you will need to figure out how to keep your setup warmer and less drafty. If your hedgehog does not improve within 30 minutes, a visit with the veterinarian is needed.
