The idea of cloning your pet sounds like a laughable waste of money, because it is. But it starts to seem a little less laughable when your own beloved pet starts getting older. If I had had a few hundred thousand dollars to spare, I know I would have half-seriously considered it for my dear little cat, who died last year. One couple that does happen to have a few hundred dollars to spare is Barry Diller and Diane, who have reportedly cloned their beloved Jack Russell Terrier (a kind of dog), Shannon, and now have two identical Jack Russell Terrier named Deena and Evita.

When your pet dies, you just want your pet back, or at least as close a copy as you can get. So it’s really no surprise that of the around 600 dogs cloned by Sooam Biotech Reaserch Foundation most were cloned for sad pet owners. The lab in Seoul, South Korea, is now the only place on the planet in the business of cloning pet dogs for pet owners.

But, in fact, the technology won’t give you your pet back. There don’t yet appear to be any studies on the behaviour of cloned pets, but research on cloned cows and pigs has so far shown marked differences in behaviour and even looks in cloned animals. The DNA is exactly the same, but there are still differences in personality and appearance.

Even if Diller and Von Furstenburg raise their new dogs in the exactly same environment in the exactly same way that they raised Shannon, the new dogs will still behave differently. “The promise of pet cloning is that your cloned pet is going to behave and look like the one you already have --- and that will not be the case,” said Professor Jorge Piedrahita at N.C. State. “We have cloned animals that were raised in the same environment, but they still didn’t act the same.”
