...wept when I read the story of cc, the cloned kitty cat [SCIENCE, Feb. 25]. As the owner of two dearly loved cats--and having gone through the anguish of losing one--I dread the coming time when I must say goodbye. But the idea of taking DNA from one of them and thinking that scientists could give me back what I had lost is abhorrent. How many people will have the misguided but understandable hope that they can somehow cheat death? Both of my cats are shelter animals, and when they were kittens, they were...
...Here, kitty, kitty!" didn't melt my heart; it broke it. Sure, the kitten named cc is a cutie, but there are millions of cuties in animal shelters begging for love. It was sensible of you to note that "given that more than 5 million unwanted cats are destroyed each year, it's hard to justify spending tens of thousands of dollars to clone a new one. Why not just adopt?" Who needs cc when there are so many originals out there and not enough homes for them all? EILEEN K. BLAU Mayaguez, Puerto Rico...
Moreover, when you do get a viable clone, it may not turn out to be much like its parent in anything but its genes. Rainbow and cc have different coloring, for example, since the coats of calicos are determined partly by genes and partly by random molecular changes during development. Temperament too is a toss-up, since it's hard to tease out how much of an animal's personality is genetically scripted and how much is shaped by environment. "The fallacy is that cloning provides a duplicate," says the Humane Society's Pacelle. Concedes Westhusin: "This...
...critics, such arguments seem like moral fig leaves. They view cc as an ethical dry run for human cloning, and they're troubled by how the rehearsal is going. "Once cloning is on its own as a commercial enterprise, there really is no oversight," says Lori Gruen, a Wesleyan University ethics professor who generally supports cloning research. Could a culture that can't agree on the morality of using human embryos to create stem cells tolerate a technology in which 86 human embryos have to die to create an 87th? "Why do it?" asks Pacelle. "It seems...
...Panayiotis Zavos, a retired University of Kentucky professor who for two years has been boasting that he would be the first to clone a human, announced last week that he has selected 10 infertile couples and is set to begin work next month. If you thought cc was hard not to love, wait until you see the first baby...
