The gray bat is also one of the bats that hibernate and while most bats would rather make the journey to warmer climates, because of the location, gray bats are willing to hibernate inside their caves. In order for a bat to go into hibernation, the cave needs to stay at forty-two to fifty-two degrees; this will keep them cool yet not too cold.

These beautiful creatures do not only use caves in the wintertime, they utilize caves in the summertime as well. They usually just have to relocate themselves to a cave near a river or a lake so they can feed during the summer.
