Weasels are grey and or brown during the summer time but are white during the winter time
God created the weasel to turn white so that it can go with the white winter.
this is like if a race car driver drives a green car so he decides to were green cloths to goes with the green car.
or if I paint my house blue but i decide to also paint my mailbox blue to go with the blue house
or Santa wears red so he decides to paint his sleigh red
God created the rabbits white during the winter so that it can go with the white snow
or if i have a red shirt so i decide to wear red pants to go with it
