Barb, I love ya, but just have to comment. I agree with the spirit of what you are saying, but the cocker spaniel, you use as an example, you may wish to purchase would never exist, then.I have no idea about hairless rats. If they were man made, then no, I don't agree with it. I don't like human kind messing with genetics or not at least trying to raise an animal to look like its naturally suppose to be.
