Is it OK to keep my hedgehog in a 105 qt. sterlite container with a heating pad set on the low setting under one end of the container? Sometimes I noticed her sleeping on the 'warmer' end and other times I noticed her on the 'cooler' end. The container is about 18" tall. Do I have to keep the lid on? There is nothing for my hedgehog to climb up on, but I am concerned that she could possibly jump out. She is only 8 weeks old, and brand new to me. Can hedgehogs jump? Can they run quickly? Thank you!
