The hands and feet of a rat are quite similar to monkeys in the sense that they have five digits with opposable thumbs. This allows them to grab objects and open them with their fingers. The coloration of a rat's hands and feet are often quite pinkish, as they are exposed without fur covering them. We can draw the hands and feet similar to the structure of human hands. The hands are also smaller than the feet, as the feet often ground the rat when they are seated or stationary. Learning how to draw a rat, easy and simple, just requires one to build up the drawing through layers, especially for finer details like feet.
