I know I have a 'rex' but I don't believe the mother/father had rex in them. Even if so, can just 1 baby come out like this from a litter of 8? Actually, now that I recall, I got this momma and her 8 babies when they were 1 day old off of a girl who's "pet" had babies and she didn't want them...so...maybe they do have rex, but still, just one??
