What is the difference between hamster pudding milk tea and silver fox?

The first picture is pudding, like the color of egg pudding, so it is called pudding. The second picture is milk tea. The back line of milk tea is so shallow that you can hardly see it. The whole body color is like bubble tea, so it is called milk tea. The colors of pudding and milk tea are easy to distinguish. One is yellow and the other is a little gray. The last one is a silver fox, with white body, a little black ears and a black line on its back. Some silver foxes grow up and the lines on their backs disappear, and the whole body turns white without any sound, so they are called the best silver foxes. These three kinds are easy to distinguish.
