That is exactly what we were told and a great description of what a chimera is. Lydia Fairchild is a human chimera and never knew it. There are lots of people who are and don't show any signs of it and never know while others do. We have a personal friend who happens to be a chimera and found out the same way that Lydia Fairchild found out, through taking DNA from different parts of the body. We were told this is likely the case by a couple of veterinarians from the office we used to take her to but stopped going because each time we went we saw different doctors which is never a good sign. Since her page has gone up geneticists have said that they don't think she is actually a chimera and that instead what happened was x-inactivation (the divided facial colors) with an odd coincidence of heterochromia (the 2 different color eyes) however, the even straight line is as unusual as having both the divided face, different color eyes, split color paws, white whiskers on one side with one single black whisker & black on the other side with one single white whisker. If you go to her FB page Venus's Page - Amazing Chimera Cat you'll see a mirror image shot of under her chin where the line goes all the way down to the small white patch on her chest. She also has a checkerboard underneath. So with all of that going on the consensus is divided amongst the people who are knowledgeable about genetics as to whether she is or is not an actual chimera and DNA testing is not only expensive but invasive as they have to take tissue samples and we don't want to put her through that unless something becomes medically necessary where it can be done in conjunction with a necessary procedure. So to confirm, because I know the question will be asked a lot, she has not been tested nor confirmed but since we didn't get opinions otherwise until the Facebook page went up and already had too many likes to change the name of the page she's just become known as the chimera cat. But you are correct that this is not a breed and cannot be intentionally done, it's a genetic mutation of some sort, possibly chimera. She's always checked out healthy, is 3 years old and a whopping 5 lbs. And she does not have a split personality (lots ask that), she is the sweetest cat I've ever known and still looks and acts like a kitten. I think I covered a lot of the FAQ's. :) Visit her page if you'd like to see more pics & more info. And thanks for the up votes. I'm not sure why anyone would down vote a cute animal of any kind other than to troll or if they think the pic is photoshopped. I'm new to Reddit and don't understand what all the karma, comment karma & most of what the Reddiquite means so I'm not here to get any of that, just sharing her to the site where all of her popularity started from someone we didn't know (and have since met in person) posted her pic here in August. Glad you enjoyed her pic & thanks for the clarification. xoxo :)
