Cows are farm animals that have the ability to interbreed with other animals to create hybrid species. Animals that have successfully been bred with cows include bison and yaks.
Oddly enough, while the buffalo and bison may look like large cows, they cannot be successfully bred with them. Cows are big, bulky animals, and they are found in a variety of colors and sizes.
Besides the common black and white coloring, cows can also come in brown, yellow, red, and even a bright orange like hue, as well as combinations of each. Some will have a body of one specific color combined with a face of a different color.
