Is Venus the two-faced cat really a chimera?

Genetics explained, with added kittens.

Venus the cat has been in the news. She has heterochromia – that is, her two eyes are different colours – as well as a perfectly placed black splodge (technical term), which makes her look like Popular Batman Villain Two-Face.

Why is she like that? One possibility is that she is a chimera. This term, taken from the mythical monster with the heads of a goat, lion and snake, refers to a real – albeit relatively rare – condition where two genetically distinct embryos merge in the womb.

A chimera is essentially the reverse of identical twins. In the latter, one fertilised egg splits completely and forms two separate embryos; in the former, two fertilised eggs merge together and grow into one child.

The cells which come from each of the fertilised eggs maintain their own character – so if one egg had genes for black hair and the other for white, the resulting chimera would have mottled black and white fur:

The thing is, Venus may not actually be a chimera.: her perfectly split face may just be a fluke placement of an otherwise normal tortoiseshell pattern. National Geographic's Katia Andreassi writes:

Female cats, said Leslie Lyons, a professor at the University of California, Davis, already have two X chromosomes so they can sport that coat without the extra X. That means Venus is not necessarily a chimera.

To find out would require genetic testing, said Lyons. With samples of skin from each side of the cat, "we can do a DNA fingerprint—just like on CSI—and the DNA from one side of the body should be different than the other."

But there is still a mystery about Venus - her single blue eye. Andreassi adds:

Cat eyes are typically green or yellow, not blue. A blue-eyed cat is typically a Siamese or else a cat with "a lot of white on them," she explained.

Venus appears to have only a white patch on her chest, which to Lyons is not enough to explain the blue eye.

Science: making cool cats cooler.

Chinese loan sharks are using nudes as collateral. Is this the grim future of revenge porn?

The economics of shame. 

When female students in Guangdong, a southern province in China, applied for a small loan, they were met with a very specific demand. Send naked photos of yourself holding your ID cards, they were told – or you won’t get the money. If you don’t pay up, we’ll make the photos public.

This is according to Nandu Daily, the area’s local newspaper, but has also been reported by the Associated Press and the Financial Times. The FT places the trend in the context of the Chinese economy, where peer to peer lending sites like Jiedaibao, the platform where the students allegedly contacted the lenders, are common. Thanks to the country’s slowing economy, the paper argues, lenders are increasingly intent on making sure they’ll be repaid.

As a result, there have also been reports of property destruction and even beatings by loan sharks. Part of the problem is that these are unregulated lenders who operate through an online platform. In this case, Jiedaibao says the agreement about photos was made via different communication channels, and told the FT: “This is an illegal offline trade between victims and lenders who did it by making use of the platform.” 

This new use of naked photos in this case, though, plays to the ways that shame is now used as a weapon, especially online – and the fact that it can essentially be monetised.

Revenge porn is a huge and growing problem. As Jon Ronson noted in his book, So You’ve Been Publicly Shamed, the internet offers a unique space in which shamings (over a naked photo, or an unwise comment) can be transmitted all over the world almost instantly. For some, this threat is simply too much to cope with, as it was for the growing number teenagers who have committed suicide after being blackmailed with naked photos

It’s telling, too, that the students targeted with these demands were, reportedly at least, women. Most victims of revenge porn are also women. The shame brought down on women who appear in these photos is not so much about their nakedness, but the implication that they've behaved in a sexual way. In China, virginity is still highly valued in marriage, and your family and friends would likely take the spread of naked photos of you extremely seriously. In Behind the Red Door, Sex in China , Richard Burger notes:

Every year, thousands of Chinese women pay for an operation to restore their hymens shortly before their wedding so that husbands can see blood on the sheets on their honeymoon night.

The strange story of these students and their loans highlights two important points. First, as anti-loan shark campaigners have argued for decades, “free choice” in signing up to extortionate fees or demands when taking out a loan is a misnomer when you’re constrained by economic need and desperation.

But second, we can’t allow the shame around female sexuality to become a commodity. We need to both protect women's rights and persecute those who share images without consent, but also fight the stigma that makes these shamings possible in the first place. It's not acceptable that the suggestion of sexual activity can still be used to ruin women's lives.
