I bet this question is a science joke. My answer for this would be Elepants. Large circus animals wear elepants to keep their legs warm. People wear pants to keep the bottom parts warm and one of the large animals that we can see in a curcus are elephants. So, yeah, elepants it is.
<u>They don't need anything to wear, they can change grow furs during winter naturally.</u>
<h2>Step-by-step explanation:</h2>
The body temperature of some animals drops and heart rate slows down to conserve energy. On the other side there are certain animals that adapt to the change in climate. They grow warmer fur or feathers or grow a layer of insulating fat. For mammals without hair, a thick layer of fat tissue is present which helps to insulate an animal's body and keep them warm.
