does the fur color of the rats make a diffirence. we feed our snakes any color rat the stores give us. as long as the size is right and they look healthy. our snakes never seemed to notice the black rat was black, or that the spotted one wasnt fulll white. i would think that with as bad eye sight as they have, they would not notice the color diffirence. but some people seem to mention that it does. if it does our snakes never noticed..
