Why do most animals contract in winter and expand in summer?
Answer:
Most animals contract in the winter so they can stay warmer like a cat. Cat's can be very long and very short, but the shortest that they get is in the winter. The longest they get is normally is in the summer when it is warmer. The reason they grow longer in the summer is that when the sun is shining on the animal the animal is spread out so much that it won't need all the heat, and they shrink shorter because the body heat will keep them warm enough to survive another winter.
